Which patch is that? I couldn't find it...
* dlls/x11drv/bitmap.c, dlls/x11drv/init.c, dlls/x11drv/opengl.c, dlls/x11drv/x11drv.h: Huw Davies huw@codeweavers.com Add an x11drv escape that returns a glx drawable. At the time the patch was submitted I was (and I am still :-) ) intrigued about the use case for this patch.
