  27 /*  FUNCTION
  28         Allocates memory for a single bitplane with the specified size in
  29         pixels.
  30
  31     INPUTS
  32         width, height - The size of the resulting bitplane in pixels.
  33
  34     RESULT
  35         A pointer to the single bitplane.
  36
  37     NOTES
  38         You should not use this function to create BitMaps. Call
  39         AllocBitMap() instead.
