Existing texture read into PBO was using GPU Blit engine in which src and
dest formats must match. With commit 61e264f4fcdba, internally stored texture
formats were no longer swizzled (BGRA instead of RGBA). This caused existing
accelerated paths to fallback to the SW slow path since the internal

Add Intel driver hook for glGetTexImage to accelerate the case of reading
texture image into a PBO. This case gets huge performance gains by using
GPU BLIT directly to PBO rather than GPU BLIT to temporary texture followed
by memcpy.
No regressions on Piglit tests with Intel driver.

Can someone from Vmware look at this very important patch?
It yields hugh performance gains on benchmarks in at least one virtualized
environment.
