- subsurd level '0' is possible again. however; it was changed to '1' because convert-to-mesh crashes. the subsurf code doesnt give a result when level is '0', causing the convert routines to either crash, or deliver empty mesh... I added a warning in the convert routine now, and dont do anything then. - changed all glFlush() in glFinish() in editobject.c, which seems to be the right magical call to show frontbuffer drawing.
