OpenGL ES only supports NPOT, not RT. So does that mean we leave these older cards in the cold? The only options I see are:
OpenGL-ES does not support full NPOT textures. It has similar restrictions to rectangle, except the texture coordinates are normalized. It may be possible to emulate them with Rectangle, but I haven't dug into all of the semantics.
Given that Rectangle Textures use different samplers in the shaders (sampler2DRect vs sampler2D) I don't think you could practically emulate this in a shader-based API.
