Right, I'm looking at a 2D library that's accelerated by OpenGL.
However, "abstraction layer" is not how I would call it, because
really it's not just about abstraction, it's going to have to
_implement_ lots of stuff, part of which will have to run on the CPU,
not on the GPU.  2D is hard in that CPU and GPU tasks tend to be
intermingled in a way that makes it quite hard to offload to the GPU.
