Hi!
Can anyone give me a hint how to image_map very high resolution pictures on
a sphere?

The (earth) sphere is basically rendered with a ~8kx4k pixel projected on
it but there are special regions of interest that should use parts of a
40kx20k file.
So NOT the whole giant bitmap is used but only a fragment that should be
patched over the lo-res bitmap.
Is it possible to put this bitmap only on a exactly defined part of the
sphere? I know this is possible with other primitives as boxes but
image_maps on a sphere are wrapped completely around or am i wrong?
Thanks in advance and Merry Christmas to all people around here!
