Use SSE2 to swizzle RGBA to BGRA
Using SSE2 can drastically reduce the amount of time it takes to do glTexImage2D. I've also added a plain-C path that's much faster than the one that was there before.

All surfaces follow D3D Y convention, i.e. (0, 0) is "top-left" rather than GL's "bottom-left". This eliminates the need to flip the default FBO to the D3D convention using additional blits when presenting and reduces VRAM usage for redundant window sized surfaces.
I took out the gl_Position.y flip from the vertex shader so FBOs are rendered
according to D3D conventions.
Texture lookups are flipped on Y to compensate. Cube map +Y and -Y faces are swapped. Y is now flipped in various other places, including uploading and reading back texture data from / to system memory, functions that take pixel space coordinates, winding order for culling, the implementation of ddy, the calculation of gl_Position and gl_FragCoord in fragment shaders and the flipping of compressed texture tiles.

Use instancing for non-array vertex attributes.
