Compiling with -DBOXX_BUGS will work around some problems with the newest
X drivers that BoXX delivers, the problems all affect use of Overlays for
normal X drawing and OpenGL drawing. Normal compilation is unchanged.
The file chooser buttons use user_data() rather than the label to decide
what to do, allowing the label to be somewhat cleaner.
Selection color on X changed to blue, to match what happens on Windows now.
