helixhorned a7eb29027f DEF command 'makepalookup', allowing indpt. specification of fog and color remapping.
The syntax is as follows:
  makepalookup { <token-list...> }
where valid tokens are
  * pal <palnum>:  the palette number, 1 .. 250
  * red <num>, green, blue (or r, g, b):  the fog color components on a 0 to 63 scale.
    Components that are not present are assumed to be 0.
  * remappal <palnum>:  the palette number to take the index remapping from, i.e. 21
    for blue -> red.  When absent, defaults to 0.
  * remapself:  when present, specifies that the remappal is the same as the 'pal'.
    This is to prevent textual redundancy when overwriting existing palookups.

Examples (best tested with tile #251):
  1) makepalookup { pal 200  red 30  remappal 23 }
     This creates palookup 200 with a fog of (30,0,0) and a blue-to-yellow remapping
     (assuming it has not been changed before)
  2) makepalookup { pal 21  red 30  remapself }
     This 'fogifies' palookup 21 with a red fog.
  3) makepalookup { pal 21  red 30 }
     This overwrites palookup 21 with a red fog, but clears the blue-to-red remapping.

The fog aspect of this command affects the GL modes just like 'fogpal', but the
remapping has no effect for hightiles.

- Also, silently clamp 'fogpal' r,g,b values to the range 0 .. 63.
