[Mesa-dev] [PATCH 3/3] i965: Allow intel_try_pbo_upload for 3D and array textures

intel_try_pbo_upload now iterates over each slice of the uploaded data and
and does a separate blit for each image. This copies in some fiddly details
store_texsubimage in order to handle the image stride correctly for 1D array
textures.
