From a55f67fcb064b4ed3019259a711b5be07f4e72ff Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Wed, 26 Nov 2014 10:20:55 +0100 Subject: [PATCH] st/mesa: Use _mesa_format_convert to implement st_GetTexImage. Instead of using _mesa_pack_rgba_span_float. This should allow us to remove that function in a later patch.
