- The overlay planes are configured as a single 8 bit PseudoColor visual.
- This is the default visual for the X server. The last entry in the
- colormap (255) is reserved for the transparency color. The overlay
- visual has a single hardware colormap, while the image planes have
- three 8 bit colormaps (for the image plane based 8 bit PseudoColor visual
- and a single 24 bit colormap for the 24 bit DirectColor visual.
