Abstract:

- Replaces the RGB macro with one that fills the highest order byte with 0xff.

We use this for the cascadia project, because it can have colors with an

alpha component. For code that is alpha-aware, include this header to make

RGB() fill the alpha byte. Otherwise, colors made with RGB will be transparent.
