  Some notes about Tinxlib
 --------------------------

 The main reason why I'm doing this is because I want to concentrate
on the game itself rather than making nice landscapes.

 I would appreciate if everyone sent their generators to me. My own
sucks, so (after asking permission, of course) I will use the one I
think looks the best. What I'm looking for is something capable of
the "real thing" - i.e. like the original game, with caves and bridges
and stuff.

  Usage
 -------

 You get three inputs. A5 is a pointer to the memory area where the
field is, and d6/d7 is the width (in bytes) and height (in pixels)
of it. The width is always a multiple of 2, so use of words and
longwords in complex algorithms is advisable.

 Please restore all registers to their original values when exiting.
Although this won't matter right now, they might in the future.

 Note that if you want to use a picture as a landscape, it's simply
a matter of unpacking it straight onto a5. But remember that it
*must* be one color only.
