Colormaps are used to store the mappings between the RGB values you ask for
and the actual, hardware-dependent values used to display those colors.
do the necessary work to allocate a color within the visual; this actually
has nothing to do with memory management, so it is important that you call
$colormap->free_colors to release those spots in the colormap
Returns a list of boolean values, telling whether the color at the corresponding spot in ... could be allocated.
