From 9b4c6da7f08f3e1ae5df2d51e2b1dcf316d19288 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 15 Aug 2014 15:21:01 -0600 Subject: mesa: minor improvements to _mesa_compute_compressed_pixelstore() Replace the gl_texture_image parameter with mesa_format since we only used the image's format. Add some comments.
