From babe26b3efa56f1afd139d5cfecbadb857a43d8f Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sun, 6 Nov 2011 18:08:36 -0800 Subject: [PATCH] mesa: Add fallback from RGB_FLOAT16 to RGBA_FLOAT16 before RGBA_FLOAT32. Not all i965 hardware can do RGB float16, and this will at least save half the memory and have expected behavior in terms of precision.
