multimap - organizes the color map as a number of smaller maps
multimap organizes the color map of the currently active framebuffer as a
number of smaller maps. Because only the normal framebuffer supports
multiple color maps, multimap should be called only while drawmode is
There are getgdesc(GD_NMMAPS) maps, each of which will have up to 256
entries, depending on the number of bitplanes available. Call getplanes
after setting the drawing mode to the desired framebuffer to determine
the color map size. getgdesc can also be called at any time to determine
the size of the color map of any framebuffer.
multimap does not take effect until gconfig is called. When called,
gconfig executes multimap requests pending for all drawing modes,
regardless of the current drawing mode.
A framebuffer's color map is used to display pixels only if the
framebuffer is in color map mode.

This routine is available only in immediate mode.
multimap is not supported on Iris Entry, Indy, XL, XS, XS24, XZ, Elan,
Extreme, and IRIS-4D RealityEngine systems.
