-# In-process ConPTY
-
-## tl;dr
-
-**Why?**
-* Out-of-process leads to out-of-sync issues.
-* Not all Console APIs have a VT equivalent.
-* Time consuming maintenance work due to poor encapsulation inside conhost.
-
-**How?**
-1. Remove `VtEngine` and translate Console API calls directly to VT.
-2. Move all Console API related code from the `Host` to the `Server` project.
-   Narrow the `IApiRoutines` interface down to its essentials.
-   Replace relevant singletons with instances.
-3. Make `Server` a standalone library with `IApiRoutines` as its primary callback interface.
-   Integrate the library in Windows Terminal.
-4. (Long term goal:) Ship the `Server` library as part of Windows. Build conhost itself on top of it.

-
-To extend on the [tl;dr](#tldr):
-* ConPTY runs outside the hosting terminal which leads to an unsolvable issue: The buffer contents between ConPTY and the terminal can go out of sync.
-  * The terminal and ConPTY may implement escape sequences differently.
-  * ...may implement text processing differently.
-  * ...may implement text reflow (resize) differently.
-  * Resizing the terminal and ConPTY is asynchronous and there may be concurrent text output.
-  * ...and it may uncover text from the scrollback, which ConPTY doesn't know about.
-* Some Console API methods cannot be represented via escape sequences and so ConPTY cannot produce them either.
-  The most basic example of this is the lack of LVB gridlines.
-* The above suggested new architecture represents a significant simplification with no loss in features.
-* ConPTY has fulfilled our needs a thousand times over, but as it's layered on top of conhost it has resulted in software decay.
-  The layer boundary has blurred over the years resulting in debugging and maintenance difficulties.
-  Lastly, its performance is insufficient and has been subject to much debate.
-  It's on us now to pay our debt and clean up the architecture so that ConPTY, conhost, and Windows Terminal can be built on top of it.
-
-Considerations:
-* A named `MUTEX` can theoretically solve parts of the out-of-sync issue, because it could be used to synchronize buffer reflow.
-  However, this requires the lock to be acquired on every API call, on top of the regular console lock, which raises ABBA deadlock concerns.
-  Making this setup not just hopefully but also provably robust, is likely to be very difficult.
-  It also doesn't solve any of the other listed problems.

-### Goals
-
-* Remove VtEngine
-* Remove `--vtmode`
-* Remove `--resizeQuirk`
-* Add buffering to `VtIo` and hook it up to the output pipe
-* Implement direct VT translations for all relevant Console APIs
-
-### Discussion
-
-The idea is that we can translate Console API calls directly to VT at least as well as the current VtEngine setup can.
-For instance, a call to `SetConsoleCursorPosition` clearly translates directly to a `CUP` escape sequence.
-Effectively, instead of translating output asynchronously in the renderer thread, we'll do it synchronously right during the Console API call.
-
-Apart from the Console APIs, the "cooked read" implementation, which handles our builtin "readline"-like text editor, will need to receive some larger changes as well.
-Its popups use `ReadConsoleOutput` and `WriteConsoleOutput` to backup and restore the affected rectangle.
-It also directly interfaces with the backing text buffer and its translation to VT relies on the existence of VtEngine.
-This results in all of the same issues that were previously outlined.
-In order to solve this, the popups need to be rewritten to use escape sequences so that they can be directly passed to the hosting terminal.
-They should also always be below the current prompt line so that we don't need to perform a potentially lossy backup/restore operation.
-
-The `--vtmode xterm-ascii` switch exists for the telnet client as it only supports ASCII as per RFC854 section "THE NVT PRINTER AND KEYBOARD".
-However, telnet is the only user of this flag and it's trivial to do there (for instance by stripping high codepoints in `WriteOutputToClient` in `telnet/console.cpp`), so there's no reason for us to keep this logic in the new code.
-
-This change will result in a significant reduction in complexity of our architecture.
-VT input from the shell or other clients will be given 1:1 to the hosting terminal, which will resolve our ordering and buffering issues.

-
-### Goals
-
-* Move the API implementation from the `Host` to the `Server` project.
-* Narrow down the `IApiRoutines` interface to its essentials.
-* Replace affected singletons with regular class instances.
-
-### Discussion
-
-The basic idea is that instead of having 3 arrows going in and out of the Server component, we got exactly 1.
-This makes the console server and its VT translation a reusable component, which we need so that we can solve the out-of-sync issues by integrating it into Windows Terminal.
-To make the Server API convenient to use, the interface needs to be narrowed down to as few methods as possible. This interface is currently called `IApiRoutines`.
-
-### API Design
-
-Design goals:
-* Low overhead<br>
-  The API should never be the reason why the terminal is slow.
-  Among others, the design includes both UTF8 and UTF16 functions, as both encodings are common on Windows and the server component should not make assumptions which one the terminal prefers.
-* Easy to use<br>
-  The Console API is unfortunately quite powerful.
-  In order to make implementing the callback interface still reasonably easy, the API should have as few methods as are needed.
-  If a complex Console API call can be expressed as a series of simpler ones, and if no other performance expectations exist, it should be expressed via the simpler ones.
-* Works even if only partially implemented<br>
-  Example: `CreateConsoleScreenBuffer` is seldomly used, but its existence adds significant complexity to the callback API design and potential implementations.
-  A terminal should either be able to return `E_NOTIMPL` and we provide a fallback, or we provide guidance for how reasonable fallbacks can be implemented (e.g. by using the xterm alt buffer in this example).
-
-> [!IMPORTANT]
-> The following API design is a rough draft just to convey the general idea.
-> It does not represent a complete, finished design.
-> This document will be updated once work on the API begins and the actual API requirements become clearer.

-// The following rules MUST be followed:
-// * Each instance represents 1 column in the terminal.
-// * Any cells that aren't representable with a single UCS-2 character, or are wider than 2 columns,
-//   must be replaced with U+FFFD. Grapheme clusters, surrogate pairs, and similar, are not allowed.
-//   Keep in mind that U+FFFD is a narrow character. It does not get the wide wide-glyph treatment below.
-// * Colors that cannot be represented via the `attributes` flags can be replaced with an approximation.
-//   Alternatively, `FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED` can be used (no `BACKGROUND` bit set).
-// * If a wide glyph (2 columns wide) is encountered, the following applies:
-//   * Create 2 consecutive CONSRV_CHAR_INFO instances (as per the first rule).
-//   * Repeat the same `character` in both instances, even if it's U+FFFD.
-//   * Assign the first instance an `attributes` flag of `COMMON_LVB_LEADING_BYTE`
-//     and the second one `COMMON_LVB_TRAILING_BYTE`.
-//   * BUT if the request for a CONSRV_CHAR_INFO only partially intersects a wide glyph, replace the character
-//     (and only the character) with U+0020 whitespace. This also means that `COMMON_LVB_LEADING/TRAILING_BYTE`
-//     should not be set, because the returned character isn't wide anymore. An example:
-//     If you have a red "猫" on top of a blue background in the buffer and a single `CONSRV_CHAR_INFO` is requested
-//     for the left half of the glyph, then you should set `character` to whitespace and `attributes` to
-//     `FOREGROUND_RED | BACKGROUND_BLUE`. Debug builds of ConPTY will assert that you do this.

-    // You don't need to keep the CONSRV_INFO struct constantly up to date, but you're allowed to do so.
-    //   For instance, it's valid to change the `.cursorPosition` when SetCursorPosition() is called.
-    //
-    // It's recommended that this function is lightweight as it may be called relatively often.
-    const CONSRV_INFO* GetInfo();
-
-    // When this method is called you're asked to apply any non-null member of the given CONSRV_INFO_CHANGE struct
-    // to the active buffer. For instance a non-null `.cursorPosition` is identical to calling `SetCursorPosition`,
-    // a non-null `.bufferSize` is a request to resize the terminal, and so on.
-    HRESULT SetInfo([in] const CONSRV_INFO_CHANGE* info);
-
-    // As explained in the CONSRV_POINT_I32 documentation, ConPTY coordinates may be outside of the VT viewport.
-    // This function is necessary in order to support this. If you assign the console buffer the same size
-    // as the VT viewport, `pos` can be translated to VT using
-    //   printf("\x1b[%d;%dC", pos.y + 1, pos.x + 1);
-    HRESULT SetCursorPosition([in] CONSRV_POINT_I32 pos);
-
-    // The Console API supports 4 gridline attributes which cannot be translated to VT.
-    // This function is necessary to represent those. If you don't plan to support the gridlines,
-    // you can translate the attributes to VT with the following code or some equivalent:
-    //   static const uint8_t lut[] = { 30, 34, 32, 36, 31, 35, 33, 37, 90, 94, 92, 96, 91, 95, 93, 97 };

-    //
-    // `attributes` of exactly `FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED` are often used to indicate the
-    // default colors in Windows Console applications, and so you may choose to translate attributes like that as:
-    //   printf("\x1b[39;49");
-    //
-    // You may also choose to support COMMON_LVB_REVERSE_VIDEO, which translates to:

-    // However, it may still read cells that have never been written to (for instance below the current viewport!).
-    // Such reads should not fail. Simply fill the `infos` array with whitespaces and a default attribute of your chosing,
-    // but `FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED` is recommended (no other bits set).

-
-After creating an _internal_ API in conhost, the next logical step is for us to extract the interface as a public one and consume it in Windows Terminal.
-At this point we should also see if we can find early adopters of the API in other projects.
-
-## Stretch Goal 4: Ship Server in Windows
-
-The console server on Windows has been an internal ABI for the longest time.
-As we have started shipping ConPTY bundled with conhost/OpenConsole to other projects, the internal ABI has become a public one.
-While we have no intention of ever breaking forward compatability of the console server with future Windows versions, it would be reassuring if the ABI long-term became internal once more.
-This will allow us complete freedom over its design, even in the decades to come, and allow us to fully shim any 3rd party applications on Windows if a ABI change were to ever happen.

-# `base/numerics`
-
-This directory contains a dependency-free, header-only library of templates
-providing well-defined semantics for safely and performantly handling a variety
-of numeric operations, including most common arithmetic operations and
-conversions.
-
-The public API is broken out into the following header files:
-
-*   `checked_math.h` contains the `CheckedNumeric` template class and helper
-    functions for performing arithmetic and conversion operations that detect
-    errors and boundary conditions (e.g. overflow, truncation, etc.).
-*   `clamped_math.h` contains the `ClampedNumeric` template class and
-    helper functions for performing fast, clamped (i.e. [non-sticky](#notsticky)
-    saturating) arithmetic operations and conversions.
-*   `safe_conversions.h` contains the `StrictNumeric` template class and
-    a collection of custom casting templates and helper functions for safely
-    converting between a range of numeric types.
-*   `safe_math.h` includes all of the previously mentioned headers.
-
-*** aside
-**Note:** The `Numeric` template types implicitly convert from C numeric types
-and `Numeric` templates that are convertable to an underlying C numeric type.
-The conversion priority for `Numeric` type coercions is:
-
-*   `StrictNumeric` coerces to `ClampedNumeric` and `CheckedNumeric`
-*   `ClampedNumeric` coerces to `CheckedNumeric`
-***
-
-[TOC]
-
-## Common patterns and use-cases
-
-The following covers the preferred style for the most common uses of this
-library. Please don't cargo-cult from anywhere else. 😉
-
-### Performing checked arithmetic type conversions
-
-The `checked_cast` template converts between arbitrary arithmetic types, and is
-used for cases where a conversion failure should result in program termination:
-
-```cpp
-// Crash if signed_value is out of range for buff_size.
-size_t buff_size = checked_cast<size_t>(signed_value);
-```
-
-### Performing saturated (clamped) arithmetic type conversions
-
-The `saturated_cast` template converts between arbitrary arithmetic types, and
-is used in cases where an out-of-bounds source value should be saturated to the
-corresponding maximum or minimum of the destination type:
-
-```cpp
-// Convert from float with saturation to INT_MAX, INT_MIN, or 0 for NaN.
-int int_value = saturated_cast<int>(floating_point_value);
-```
-
-### Enforcing arithmetic type conversions at compile-time
-
-The `strict_cast` emits code that is identical to `static_cast`. However,
-provides static checks that will cause a compilation failure if the
-destination type cannot represent the full range of the source type:
-
-```cpp
-// Throw a compiler error if byte_value is changed to an out-of-range-type.
-int int_value = strict_cast<int>(byte_value);
-```
-
-You can also enforce these compile-time restrictions on function parameters by
-using the `StrictNumeric` template:
-
-```cpp
-// Throw a compiler error if the size argument cannot be represented by a
-// size_t (e.g. passing an int will fail to compile).
-bool AllocateBuffer(void** buffer, StrictCast<size_t> size);
-```
-
-### Comparing values between arbitrary arithmetic types
-
-Both the `StrictNumeric` and `ClampedNumeric` types provide well defined
-comparisons between arbitrary arithmetic types. This allows you to perform
-comparisons that are not legal or would trigger compiler warnings or errors
-under the normal arithmetic promotion rules:
-
-```cpp
-bool foo(unsigned value, int upper_bound) {
-  // Converting to StrictNumeric allows this comparison to work correctly.
-  if (MakeStrictNum(value) >= upper_bound)
-    return false;
-```
-
-*** note
-**Warning:** Do not perform manual conversions using the comparison operators.
-Instead, use the cast templates described in the previous sections, or the
-constexpr template functions `IsValueInRangeForNumericType` and
-`IsTypeInRangeForNumericType`, as these templates properly handle the full range
-of corner cases and employ various optimizations.
-***
-
-### Calculating a buffer size (checked arithmetic)
-
-When making exact calculations—such as for buffer lengths—it's often necessary
-to know when those calculations trigger an overflow, undefined behavior, or
-other boundary conditions. The `CheckedNumeric` template does this by storing
-a bit determining whether or not some arithmetic operation has occured that
-would put the variable in an "invalid" state. Attempting to extract the value
-from a variable in an invalid state will trigger a check/trap condition, that
-by default will result in process termination.
-
-Here's an example of a buffer calculation using a `CheckedNumeric` type (note:
-the AssignIfValid method will trigger a compile error if the result is ignored).
-
-```cpp
-// Calculate the buffer size and detect if an overflow occurs.
-size_t size;
-if (!CheckAdd(kHeaderSize, CheckMul(count, kItemSize)).AssignIfValid(&size)) {
-  // Handle an overflow error...
-}
-```
-
-### Calculating clamped coordinates (non-sticky saturating arithmetic)
-
-Certain classes of calculations—such as coordinate calculations—require
-well-defined semantics that always produce a valid result on boundary
-conditions. The `ClampedNumeric` template addresses this by providing
-performant, non-sticky saturating arithmetic operations.
-
-Here's an example of using a `ClampedNumeric` to calculate an operation
-insetting a rectangle.
-
-```cpp
-// Use clamped arithmetic since inset calculations might overflow.
-void Rect::Inset(int left, int top, int right, int bottom) {
-  origin_ += Vector2d(left, top);
-  set_width(ClampSub(width(), ClampAdd(left, right)));
-  set_height(ClampSub(height(), ClampAdd(top, bottom)));
-}
-```
-
-*** note
-<a name="notsticky"></a>
-The `ClampedNumeric` type is not "sticky", which means the saturation is not
-retained across individual operations. As such, one arithmetic operation may
-result in a saturated value, while the next operation may then "desaturate"
-the value. Here's an example:
-
-```cpp
-ClampedNumeric<int> value = INT_MAX;
-++value;  // value is still INT_MAX, due to saturation.
---value;  // value is now (INT_MAX - 1), because saturation is not sticky.
-```
-
-***
-
-## Conversion functions and StrictNumeric<> in safe_conversions.h
-
-This header includes a collection of helper `constexpr` templates for safely
-performing a range of conversions, assignments, and tests.
-
-### Safe casting templates
-
-*   `as_signed()` - Returns the supplied integral value as a signed type of
-    the same width.
-*   `as_unsigned()` - Returns the supplied integral value as an unsigned type
-    of the same width.
-*   `checked_cast<>()` - Analogous to `static_cast<>` for numeric types, except
-    that by default it will trigger a crash on an out-of-bounds conversion (e.g.
-    overflow, underflow, NaN to integral) or a compile error if the conversion
-    error can be detected at compile time. The crash handler can be overridden
-    to perform a behavior other than crashing.
-*   `saturated_cast<>()` - Analogous to `static_cast` for numeric types, except
-    that it returns a saturated result when the specified numeric conversion
-    would otherwise overflow or underflow. An NaN source returns 0 by
-    default, but can be overridden to return a different result.
-*   `strict_cast<>()` - Analogous to `static_cast` for numeric types, except
-    this causes a compile failure if the destination type is not large
-    enough to contain any value in the source type. It performs no runtime
-    checking and thus introduces no runtime overhead.
-
-### Other helper and conversion functions
-
-*   `IsValueInRangeForNumericType<>()` - A convenience function that returns
-    true if the type supplied as the template parameter can represent the value
-    passed as an argument to the function.
-*   `IsTypeInRangeForNumericType<>()` - A convenience function that evaluates
-    entirely at compile-time and returns true if the destination type (first
-    template parameter) can represent the full range of the source type
-    (second template parameter).
-*   `IsValueNegative()` - A convenience function that will accept any
-    arithmetic type as an argument and will return whether the value is less
-    than zero. Unsigned types always return false.
-*   `SafeUnsignedAbs()` - Returns the absolute value of the supplied integer
-    parameter as an unsigned result (thus avoiding an overflow if the value
-    is the signed, two's complement minimum).
-
-### StrictNumeric<>
-
-`StrictNumeric<>` is a wrapper type that performs assignments and copies via
-the `strict_cast` template, and can perform valid arithmetic comparisons
-across any range of arithmetic types. `StrictNumeric` is the return type for
-values extracted from a `CheckedNumeric` class instance. The raw numeric value
-is extracted via `static_cast` to the underlying type or any type with
-sufficient range to represent the underlying type.
-
-*   `MakeStrictNum()` - Creates a new `StrictNumeric` from the underlying type
-    of the supplied arithmetic or StrictNumeric type.
-*   `SizeT` - Alias for `StrictNumeric<size_t>`.
-
-## CheckedNumeric<> in checked_math.h
-
-`CheckedNumeric<>` implements all the logic and operators for detecting integer
-boundary conditions such as overflow, underflow, and invalid conversions.
-The `CheckedNumeric` type implicitly converts from floating point and integer
-data types, and contains overloads for basic arithmetic operations (i.e.: `+`,
-`-`, `*`, `/` for all types and `%`, `<<`, `>>`, `&`, `|`, `^` for integers).
-However, *the [variadic template functions
-](#CheckedNumeric_in-checked_math_h-Non_member-helper-functions)
-are the prefered API,* as they remove type ambiguities and help prevent a number
-of common errors. The variadic functions can also be more performant, as they
-eliminate redundant expressions that are unavoidable with the with the operator
-overloads. (Ideally the compiler should optimize those away, but better to avoid
-them in the first place.)
-
-Type promotions are a slightly modified version of the [standard C/C++ numeric
-promotions
-](http://en.cppreference.com/w/cpp/language/implicit_conversion#Numeric_promotions)
-with the two differences being that *there is no default promotion to int*
-and *bitwise logical operations always return an unsigned of the wider type.*
-
-### Members
-
-The unary negation, increment, and decrement operators are supported, along
-with the following unary arithmetic methods, which return a new
-`CheckedNumeric` as a result of the operation:
-
-*   `Abs()` - Absolute value.
-*   `UnsignedAbs()` - Absolute value as an equal-width unsigned underlying type
-    (valid for only integral types).
-*   `Max()` - Returns whichever is greater of the current instance or argument.
-    The underlying return type is whichever has the greatest magnitude.
-*   `Min()` - Returns whichever is lowest of the current instance or argument.
-    The underlying return type is whichever has can represent the lowest
-    number in the smallest width (e.g. int8_t over unsigned, int over
-    int8_t, and float over int).
-
-The following are for converting `CheckedNumeric` instances:
-
-*   `type` - The underlying numeric type.
-*   `AssignIfValid()` - Assigns the underlying value to the supplied
-    destination pointer if the value is currently valid and within the
-    range supported by the destination type. Returns true on success.
-*   `Cast<>()` - Instance method returning a `CheckedNumeric` derived from
-    casting the current instance to a `CheckedNumeric` of the supplied
-    destination type.
-
-*** aside
-The following member functions return a `StrictNumeric`, which is valid for
-comparison and assignment operations, but will trigger a compile failure on
-attempts to assign to a type of insufficient range. The underlying value can
-be extracted by an explicit `static_cast` to the underlying type or any type
-with sufficient range to represent the underlying type.
-***
-
-*   `IsValid()` - Returns true if the underlying numeric value is valid (i.e.
-    has not wrapped or saturated and is not the result of an invalid
-    conversion).
-*   `ValueOrDie()` - Returns the underlying value. If the state is not valid
-    this call will trigger a crash by default (but may be overridden by
-    supplying an alternate handler to the template).
-*   `ValueOrDefault()` - Returns the current value, or the supplied default if
-    the state is not valid (but will not crash).
-
-**Comparison operators are explicitly not provided** for `CheckedNumeric`
-types because they could result in a crash if the type is not in a valid state.
-Patterns like the following should be used instead:
-
-```cpp
-// Either input or padding (or both) may be arbitrary sizes.
-size_t buff_size;
-if (!CheckAdd(input, padding, kHeaderLength).AssignIfValid(&buff_size) ||
-     buff_size >= kMaxBuffer) {
-  // Handle an error...
-} else {
-  // Do stuff on success...
-}
-```
-
-### Non-member helper functions
-
-The following variadic convenience functions, which accept standard arithmetic
-or `CheckedNumeric` types, perform arithmetic operations, and return a
-`CheckedNumeric` result. The supported functions are:
-
-*   `CheckAdd()` - Addition.
-*   `CheckSub()` - Subtraction.
-*   `CheckMul()` - Multiplication.
-*   `CheckDiv()` - Division.
-*   `CheckMod()` - Modulus (integer only).
-*   `CheckLsh()` - Left integer shift (integer only).
-*   `CheckRsh()` - Right integer shift (integer only).
-*   `CheckAnd()` - Bitwise AND (integer only with unsigned result).
-*   `CheckOr()`  - Bitwise OR (integer only with unsigned result).
-*   `CheckXor()` - Bitwise XOR (integer only with unsigned result).
-*   `CheckMax()` - Maximum of supplied arguments.
-*   `CheckMin()` - Minimum of supplied arguments.
-
-The following wrapper functions can be used to avoid the template
-disambiguator syntax when converting a destination type.
-
-*   `IsValidForType<>()` in place of: `a.template IsValid<>()`
-*   `ValueOrDieForType<>()` in place of: `a.template ValueOrDie<>()`
-*   `ValueOrDefaultForType<>()` in place of: `a.template ValueOrDefault<>()`
-
-The following general utility methods is are useful for converting from
-arithmetic types to `CheckedNumeric` types:
-
-*   `MakeCheckedNum()` - Creates a new `CheckedNumeric` from the underlying type
-    of the supplied arithmetic or directly convertible type.
-
-## ClampedNumeric<> in clamped_math.h
-
-`ClampedNumeric<>` implements all the logic and operators for clamped
-(non-sticky saturating) arithmetic operations and conversions. The
-`ClampedNumeric` type implicitly converts back and forth between floating point
-and integer data types, saturating on assignment as appropriate. It contains
-overloads for basic arithmetic operations (i.e.: `+`, `-`, `*`, `/` for
-all types and `%`, `<<`, `>>`, `&`, `|`, `^` for integers) along with comparison
-operators for arithmetic types of any size. However, *the [variadic template
-functions
-](#ClampedNumeric_in-clamped_math_h-Non_member-helper-functions)
-are the prefered API,* as they remove type ambiguities and help prevent
-a number of common errors. The variadic functions can also be more performant,
-as they eliminate redundant expressions that are unavoidable with the operator
-overloads. (Ideally the compiler should optimize those away, but better to avoid
-them in the first place.)
-
-Type promotions are a slightly modified version of the [standard C/C++ numeric
-promotions
-](http://en.cppreference.com/w/cpp/language/implicit_conversion#Numeric_promotions)
-with the two differences being that *there is no default promotion to int*
-and *bitwise logical operations always return an unsigned of the wider type.*
-
-*** aside
-Most arithmetic operations saturate normally, to the numeric limit in the
-direction of the sign. The potentially unusual cases are:
-
-*   **Division:** Division by zero returns the saturated limit in the direction
-    of sign of the dividend (first argument). The one exception is 0/0, which
-	returns zero (although logically is NaN).
-*   **Modulus:** Division by zero returns the dividend (first argument).
-*   **Left shift:** Non-zero values saturate in the direction of the signed
-    limit (max/min), even for shifts larger than the bit width. 0 shifted any
-    amount results in 0.
-*   **Right shift:** Negative values saturate to -1. Positive or 0 saturates
-    to 0. (Effectively just an unbounded arithmetic-right-shift.)
-*   **Bitwise operations:** No saturation; bit pattern is identical to
-    non-saturated bitwise operations.

-// The following helper template addresses a corner case in range checks for

-// but larger precision (e.g. float -> unsigned). The problem is as follows:
-//   1. Integral maximum is always one less than a power of two, so it must be
-//      truncated to fit the mantissa of the floating point. The direction of
-//      rounding is implementation defined, but by default it's always IEEE
-//      floats, which round to nearest and thus result in a value of larger
-//      magnitude than the integral value.
-//      Example: float f = UINT_MAX; // f is 4294967296f but UINT_MAX
-//                                   // is 4294967295u.
-//   2. If the floating point value is equal to the promoted integral maximum
-//      value, a range check will erroneously pass.
-//      Example: (4294967296f <= 4294967295u) // This is true due to a precision
-//                                            // loss in rounding up to float.
-//   3. When the floating point value is then converted to an integral, the
-//      resulting value is out of range for the target integral type and
-//      thus is implementation defined.
-//      Example: unsigned u = (float)INT_MAX; // u will typically overflow to 0.
-// To fix this bug we manually truncate the maximum value when the destination
-// type is an integral of larger precision than the source floating-point type,
-// such that the resulting maximum is represented exactly as a floating point.
