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 
       and  LoadRGB4 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() to
	query it or  SetRGB4CM 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.
