"attached you'll find some modifications to Producer, osgGA and osgProducer to enable Mac OS X support for + scrollwheels, + mightymouse-srollballs + new tracking-pads with scroll feature + tablet-support (pressure, proximity and pointertype) (Wacom only tested) I think there was a bug in the windows-implementation of scroll-wheel support (wrong order of ScrollingMotion-enum, casting problem) which is fixed now. The scrollwheel-code is a bit klunky across platforms, some devices on OS X can report an absolute delta in pixel-coordinates not only the direction, so for now there is scrollingMotion (which describes the direction) and scrolldeltax and scrolldeltay. I decided to leave the scrollingmotion-stuff to not break old code relying on this."
