From 88a8830390c8c7557d2e852dcef94ae6f04eb6b5 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Fri, 25 Jul 2014 17:38:22 +0100 Subject: [PATCH] mesa/main: Modify generate_mipmap_compressed to cope with float textures Once we add BPTC texture support we will need to generate mipmaps for compressed floating point textures too. Most of the code seems to already be there but it just needs a few extra lines to get it to use GL_FLOAT instead of GL_UNSIGNED_BYTE as the type for the temporary buffers.
