Create a gc using XCreateGC. Set the foreground of the GC to W_FG ^ W_BG. Create a drawable with background W_BG using XCreateWindow. Fill the polygon on the drawable using XFillPolygon. Set the GC clipmask to the region using XSetRegion. Set the graphics function of the GC to GXxor using XSetFunction. Fill the drawable using XFillRectangle.
