Subclasses must implement BuildTextureRGBA which will be called each frame.

Called each frame to generate the texture to render on the terrain.
data
is w*h*4 bytes, where w and h are the terrain size multiplied by texelsPerTile. data
defaults to fully transparent, and should be filled with data in RGBA order.
Implemented in HierarchicalOverlay, LongOverlay, AtlasOverlay, and TerritoryOverlay.
Returns an arbitrary color, for subclasses that want to distinguish different integers visually.
