Original Pull Request: https://github.com/microsoft/terminal/pull/12207

State: closed
Merged: Yes

This commit replaces our use of size_t to represent VT parameters with
int32_t. While unsigned integers have the inherent benefit of being less
ambiguous and enjoying two's complement, our buffer coordinates use signed
integers. Since a number of VT functions need to convert their parameters
to coordinates, this commit makes the conversion easier.
The benefit of this change becomes even more apparent if one considers
that a number of places performed unsafe conversions
of their size_t parameters to int or short already.

Files that had to be modified were converted to use til
wrappers instead of COORD or SMALL_RECT wherever possible.

This commit contains about 20% of the work for #4015.

PR Checklist

  • I work here
  • Tests added/passed

Validation Steps Performed

I'm mostly relying on our unit tests here. Both OpenConsole and WT appear to work fine.
