   FUNCTION
  Convert RGB to a palette.

   INPUTS
  MPp      - Contains the Red,Green and Blue chunky pixels
             and the Width and Height
  maxcol   - The number of colours in the palette.
  pal      - The palette. This is a 768 byte array.
             pal[0] to pal[maxcol] hold the Red palette
             pal[256] to pal[256+maxcol] hold the Green palette
             pal[512] to pal[512+maxcol] hold the Blue palette
  bit12    - If set then only the top 4 bits of the palette
             are used and the mapping is far quicker.

   RESULT
  The data pointed to by MPp->Red is updated to the palette mapped image.

   NOTES
  If there is insufficient memory then bit12 is treated as false.
