From 05d4b4c72a5089885c1515833e34177607c2c511 Mon Sep 17 00:00:00 2001 From: Rhys Weatherley Date: Tue, 8 Dec 2009 11:02:46 +1000 Subject: Fix GL_BGRA formats under OpenGL/ES systems OpenGL/ES requires that the internal and external formats be the same when calling glTexImage2D(). This caused problems with devices that had the GL_EXT_bgra extension. This change makes the formats the same just before the upload and also makes sure that the pixel type is GL_UNSIGNED_BYTE when GL_BGRA is used. No change for desktop systems.
