The cursor may not be displayed in the colormap of the current
colormap focus window.  Some servers have separate hardware cursors
that use a different colormap.  Given this possibility it is wise
that the cursor colors are set in RGB values.

If a server draws a cursor in the frame buffer it should recompute the
cursor indices to match the requested RGB values whenever it installs a
new colormap.  If the X server doesn't update the cursor to match the
colormap, then there isn't much that a client can do about it.
