LibGGI is a fullscreen graphics API and as such does not have the notion
of "allocating" or freeing colors.

If you want to reduce color flickering on windowing systems you can
use GGI_PALETTE_DONTCARE as documented in the ggiSetPalette() man-page.

Another, less nice on non-X targets, alternative is to close and re-open
the visual when activating/de-activating the image-viewer.
