And the APIs are complicated. Traditional (1.1) OpenGL can only do this to and from the framebuffer, not between textures. The last time I looked at this problem, about 2 years ago, there were a bunch of extensions being proposed that would represent all memory areas on the graphics card (vertex buffers, textures, framebuffers, depthbuffers, etc...) with a unified API that was tentatively called the "uberbuffer". I'm not sure what happened to this, or what the status is of driver support on modern cards.
