The function SkyMap::drawOverlays() is designed to facilitate this kind of 
thing.  Check out drawZoomBox() and drawTelescopeSymbols() for examples (both 
are called in drawOverlays() ).

Then you just have to call update() inside mouseMoveEvent() when anglemode is 
on to refresh the line; update() will just repaint the stored sky pixmap and 
redraw the overlays on top of it (the overlays are the infoboxes, the target 
symbols, and the zoom box).

Hope that makes sense!

Jason
