We want to save memory and make the background into anything the platform specifies, for instance a GL shader or a smart tiling implementation. For that purpose, the platform API is changing to make the existing checkerBuffer() into a more versatile fillBuffer(). In turn, we want to get rid of the existing customizable background image setting and just use whatever the system is providing. And also fix consistency for the overscroll color API. Patch below.
