Yeah, I would rather drop the version 4/5 logic rather than just go 
halfway and try to eliminate the QtOpenGL module while still supporting 
Qt4 for the main GUI.  Trying to accommodate both versions adds a lot to 
the complexity, especially on systems that might have both (maybe 
partially) installed.
