Nearly finished Moon eclipse rendering. Something is maybe wrong with the size of the Earth's shadow. It is currently based on http://de.wikipedia.org/w/index.php?title=Datei:MondFi.svg&filetimestamp=20090318104003& if nothing has been miscalculated.

Change Summary:

That is the current state of the work.

Problems:
- Moving the sky globe also moves the shadow, this is the effect of the following: The shadow and the moon are separately painted to the sky but as normal pixmaps, so from our viewpoint the distance between them disappears at the edge of the screen so they overlap each other.
- In magnified case the clipping works well, but in nonmagnified case some pixel is missing, the magnified case would be ugly with more added pixels to the clipping.

Diff:

Revision 4 (+136 -12)
