Patch from Melchior Franz:

Here is a patch that fixes a little problem in dome.cxx: The fog_color
is created in a sgVec3 (227) but then handed over to ::repaint(), which
expects a sgVec4 (282). Then (343) center_color (although defined as
sgVec4) is only initialized with 3 values, but later (441) assigned to
'slot' via sgCopyVec4.
