Original Pull Request: https://github.com/microsoft/terminal/pull/12242

State: closed
Merged: Yes

This commit extracts DirectWrite related shader code into dwrite.hlsl
and adds support for ClearType blending.

Additionally the following changes are piggybacked into this commit:

  • Some incorrect code around fallback glyph sizing was removed as
    this is already accomplished by CreateTextLayout internally
  • Hot-reload failed to work with dwrite.hlsl as the pFileName
    parameter was missing
  • Legibility of the dotted underline was improved by increasing
    the line gap from 1:1 to 3:1

Part of #9999.
