From a67b18e5a7c47fd38d526bac409c04daedec9f8c Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sun, 28 Apr 2013 23:33:39 -0700 Subject: [PATCH] mesa: Add comments about bit-ordering of new XRGB/XBGR formats. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Marek added these new formats in commit f9fa725690c470daf308, but without comments relating to the packing. Sometimes the naming is confusing, so these comments are helpful in determining whether two formats are compatible. The new comments are based on my reading of format_unpack.c.
