    window: Remove support for colormaps
    
    While the ICCCM mandates the use of this, it's not necessary under
    a composited environment from my understanding, and it's a flat
    out no-op under XWayland.
    
    Looking at the other rootless servers like Xwin/Xquartz, it seems
    that they contain code for colormap emulation, but they're actually
    never used -- a bug prevents the code from ever being called. Given
    that it's been this way since 2003, I'm going to hazard a guess that
    not many apps using colormaps. Kill them off.
