   NAME   
  RescaleMPImage -- Scales an image created by LoadMPImage() (V3)

   SYNOPSIS
  error = RescaleMPImage(MPi, x, y)
  D0                     A0   D0 D1

  BOOL RescaleMPImage(struct MPImage *, UWORD, UWORD);

   FUNCTION
  Scales an Image loaded by LoadMPImage() to new width and height.

   INPUTS
  MPi - Image loaded by LoadMPImage
  x   - New width of image
  y   - New height of image

   RESULT
  error - 1 for success, 0 for failure.
          Use MPImageErrorMessage() to get error.

   EXAMPLE

   NOTES
  Rescaling of bitmaps is done using BitMapScale().
  Other rescaling is done using custom code with smoothing.

  If this function fails then the MPImage is no longer usable and
  FreeMPImage() should be called to free it.

  Version 4.3 is faster for RGB.

   BUGS
  Bitmaps may not scale smoothly.
  The rescaling of EGS images is not efficent.
