Thanks much! In my testing I only needed the .xbm files. Must of only 
searched for xbgmap.xpm when deciding to lose both the *.xpm files...

Aside: In the whither thread you gently tossed an arrow at the Simple 
DirectMedia Layer use. I've done a little debug work around 1.2 hangs 
and povr/hgpovray have SDL2.0 and x11 support thanks to Jerome.

My understanding is that SDL1.2 was chosen for v3.7 because of problems 
with x11 at the time - which perhaps are not all that different from 
what we still see with x11 today.

In my povr/POV-Ray use all three display options still have issues with 
x11 being the worst behaving. The x11 and SDL1.2 options suffer from 
occasional hangs requiring a kill command to stop with x11 being worse. 
Not seen the hangs in SDL2.0, but there is once in a while a had row of 
pixels usually in the upper left on scaling to fit a window. I recommend 
SDL2.0 use today if you have a choice.

Others can speak to it better than me, but I believe some of the issues 
come to our code architecture being non-standard with respect to 
interface handling. It would be more normal to have x11/SDL - or 
whatever interface handler be the main loop from which everything else 
is spawned.
