From b1ab02d9c0cc11ba8ef4efaba9452d644b6a0811 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Fri, 27 Feb 2015 12:29:03 -0800 Subject: [PATCH] meta/TexSubImage: Stash everything other than PIXEL_TRANSFER/store in meta_begin Previously, there were bugs where if the app set a scissor it could affect the area of the texture that was downloaded. There was also potential that the framebuffer SRGB state could affect downloads. This ensures that those will get saved/restored and can't affect the texture download.
