If the glDrawPixels size changed, we leaked the previously cached
texture, if there was one. This patch fixes the reference counting,
adds a refcount assertion check, and better handles potential malloc()
failures.
Tested with a modified version of the drawpix Mesa demo which changed
the image size for each glDrawPixels call.

Guard band clipping speeds up rasterization for primitives that are
partially off-screen. This change in particular results in small
framerate improvements in a wide range of games.

always go to VRAM.

The closed driver does this, but it looks at base_level and last_level
and uses a conditional assignment, which LLVM can't generate on SGPRs.
That led me to invent this solution that abuses the image descriptor.
