From 82ddd1129e76b8bb978497df2940d1449a848551 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 13 Feb 2012 08:49:34 -0700 Subject: [PATCH] mesa: add MESA_FORMAT_Z32_FLOAT_X24S8 case in format unpack code Added in _mesa_pack_uint_24_8_depth_stencil_row(). This could be hit by something like glDrawPixels(GL_DEPTH_STENCIL, GL_UNSIGNED_INT_24_8) into a MESA_FORMAT_Z32_FLOAT_X24S8 buffer.
