It is much easier to see where performance is going when you color the performance markers.
The coloring of markers is supported in most profilers in Windows that can read the D3D perf markers (such as Intel GPA, NSight, etc) and it is also supported on Xbox One, and PS4.
Do you think that I should make a pull request with this change? This only adds a uint32 with the ARGB color to set. Supported platforms will use the color, unsupported platforms will just ignore it.
