It's not that simple.  The textures repeat every 6 m in the course
(TEX_SCALE in textures.h).  If you use tux_course_dim to set the width
of the course to 6 * (width of heightmap in pixels), and the length of
the course to 6 * (height of heightmap in pixels), then you should get
one complete texture image per course quad.  Hopefully they'll be
aligned properly too, though I haven't tried it.  The problem then is
that the mesh of the terrain will be very coarse -- so instead you could
repeat you bullseye in an X by X grid in the texture file, and then set
the dimesions of the course to 6/X * (width/height of heightmap in pixels).

This is a hack, of course, but then again so is what you're trying to
do. :) Also note that I haven't tried it, but I think it *should*
work...

Great!
