There were 2 issues with it:
- resource_copy_region doesn't allow different sample counts of both src
  and dst, which can occur if we blit between a window and a FBO, and
  the window has an MSAA colorbuffer and the FBO doesn't.
  (this was the main motivation for using pipe->blit)
- blitting from or to a non-zero layer/slice/face was broken, because
  rtt_face and rtt_slice were ignored.

blit_copy_pixels is now used even if the formats and orientation of
framebuffers don't match.

8 years agor600g: upsample and downsample MSAA resources for transfers

r600g: upsample and downsample MSAA resources for transfers

We did downsample (=resolve) MSAA resources to make ReadPixels work with MSAA
GLX visuals, which was enough for read-only color-only transfers.

This commit makes write color transfers and depth-stencil transfers work
in a similar manner. It does downsampling in transfer_map and upsampling
in transfer_unmap.
