ggiSetColorfulPalette - Set a palette with a full range of all colors
int ggiSetColorfulPalette(ggi_visual_t vis);
LibGGI guarantees that there will be a default palette when a
palettized mode is set. What this default is, however, dependent on
the visual. For example, the X target deliberately avoids setting all
colors to avoid color-flashing when moving between windows.
Applications that want to ensure that they have a full scale of all
colors can call ggiSetColorfulPalette after mode set. This function
uses a smarter color allocation scheme, causing good colors but still
minimal flashing in windowed targets.
ggiSetColorfulPalette returns the number of the first entry changed.
<0 indicate a ggi-error(3).
