* new feature: rendering large images now displays correctly zoomed down in an imagewindow. The fact that it didn't also caused unpredictable slowdowns at various systems (tested osx, win). Of course after rendering you can still zoom in/out as usual. * there was code that limits the maximum size of an imagewindow, keeping a small border around it free. By increasing the border 15 pixels I got huge speedup at OSX. Still looks good though... Needs more research what is happening here, maybe we need a user setting for it... but i rather implement the usage of the internal ImageWindow first. Still unsolved: 24 bits windows opening... I don't dare yet hacking in it Ghost.
