[Mesa-dev] [PATCH 03/12] st/mesa: make st_init_extensions context-independent
Marek Olšák
maraeo at gmail.com
Sun Aug 3 08:18:26 PDT 2014
From: Marek Olšák <marek.olsak at amd.com>
Setting Const.MaxSamples needed a rework, so that it doesn't call
st_choose_format, which depends on st_context.
Other than that, there is no change in functionality.
