From 5f29dca0700c7bc87c891b1d7653ae3d798407d4 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 24 May 2013 11:42:10 -0700 Subject: intel: Rebuild PBO blit glTexImage() on top of miptrees. This will ensure that we have resolves if we ever extend this to glTexSubImage(), and fixes missing image start offset handling. The texture buffer alloc ended up getting moved up, because we want to look at the format of the image's actual mt to see if we'll end up blitting the right thing, in the case of packed depth/stencil uploads. This is the last caller of intelEmitCopyBlit() on a miptree-wrapped BO.
