From 6bf0f6ae86dae14ed0348e5fccf75c43302ad502 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 20 Jan 2012 13:59:37 -0800 Subject: meta: Detect currently-unsupported integer CopyTexSubImage and complain. This code is unprepared for handling integer (particularly, the baseFormat of the TexFormat comes out as GL_RGBA, not GL_RGBA_INTEGER, so the direct call of Driver.ReadPixels crashes due to the int vs non-int error checking not having happened). I'm frankly tempted to convert this code to MapRenderbuffer/MapTexImage rather than doing it as meta ops, now that we have that support. Improves the remaining crash in Intel oglconform for int-textures to just a rendering failure. NOTE: This is a candidate for the 8.0 branch.
