Gtk2::Gdk::Colormap - wrapper for GdkColormap
DESCRIPTION
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. The "$colormap->alloc_color" and "$colormap->alloc_colors" methods 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 allocated by "alloc_color" and "alloc_colors".
