NAME
       GetColorMap -- allocate and initialize Colormap


   SYNOPSIS
       cm = GetColorMap( entries )
       d0		    d0

	struct ColorMap *GetColorMap( ULONG);

   FUNCTION
       Allocates, initializes and returns a pointer to a ColorMap
       data structure, later enabling calls to SetRGB4/SetRGB32
       and LoadRGB4/LoadRGB32 to load colors for a view port. The
       ColorTable pointer in the ColorMap structure points to a
       hardware specific colormap data structure. You should not
       count on it being anything you can understand. Use
       GetRGB4()/GetRGB32() to query it or SetRGB4CM/SetRGB32CM
       to set it directly.

   INPUTS
	entries - number of entries for this colormap

    RESULT
	The pointer value returned by this routine, if nonzero,
       may be stored into the ViewPort.ColorMap pointer.
       If a value of 0 is returned, the system was unable
       to allocate enough memory space for the required
       data structures.
