Warning
gdk_rgb_set_install is deprecated and should not be used in newly-written code.
If install is TRUE, directs GdkRGB to always install a new "private"
colormap rather than trying to find a best fit with the colors already
allocated. Ordinarily, GdkRGB will install a colormap only if a
sufficient cube cannot be allocated.
A private colormap has more colors, leading to better quality display,
but also leads to the dreaded "colormap flashing" effect.
