Can you move this variable to be a member of the HUDLayerImpl, and make this
file expose the array of colors instead of one at a time. Then HUDLayerImpl can
just grab the color it wants to use directly.

+    (s_currentPaintRectColor + 1) % arraysize(kPaintRectColors);
 }
 
 // Property-changed rects in blue.
