BGE Dome: bugfix - Warp Mesh not working

Fix: to swap the drawing order for the warp mesh polygon
The code was drawing CW instead of CCW.

It would work in some cases where the drawing flags would allow for the
back faces to be visible.

More specifically the alternative fix were:
glDisable ( GL_CULL_FACE );
glFrontFace( GL_CW );

Bug originally reported in the small_planetarium mailing list.
This bug fix was a comissioned job by a group who prefer not to be
credited. Thanks regardless.
