Planar mappings don't skew correctly.


Defining Float == float doesn't breaks refraction.

fracland does not function on some machines.  It ran perfectly on my 
NetBSD i486 machine, and on a DECstation 5000/240, but fails on an Alpha.
In libshade/stats.c, the pointers seem to do odd things with fracland:
otmp->methods == 140022490, obj->methods == 140022990
otmp->methods == 140022090, obj->methods == 140022990
otmp->methods == 140022110, obj->methods == 140022990
otmp->methods == 140022990, obj->methods == 40022b90
                            ^^^^^^^^^^^^^^^^^^^^^^^^  ``pointer'' to fracland
methods.  I suspect dereferencing this is a Bad Thing.  Odd, add 0x10000000 to it
and it almost looks valid.

There is some sort of bug in rotspline dealing with a stray shadow.  If the
following scene is rendered in preview (-p) or no-shadow (-n) mode, all is
well, but with shadows on a band of ``shadow'' appears on the object.

rotspline brown 0 0 0 1   1.15 0 0 8 1   0.20
light 0.5 point 30 -40 0
lookp 0 0 2.5
eyep -5 -15 2.5
