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.
