From 6a433b67ca15fd1ea58334e607f867554f227451 Mon Sep 17 00:00:00 2001

Subject: glx: Fix lifetime tracking for pixmaps
GLX pixmaps take a reference on the underlying pixmap; X and GLX pixmap
IDs can be destroyed in either order with no error. Only windows need
to be tracked under both XIDs.
Fixes piglit/glx-pixmap-life.
