1.test is used internally to adjust for example Gui.ms
you shouldn't really use it
2. hardware cursors do not support smooth transparencies (its Windows/DirectX limitation, not EE)
3. ill add those methods in the next release, in meantime please base on these codes:
Region& Region::scrollY (Flt delta ){slidebar[1].scroll (delta ); return T;}
Region& Region::scrollToY (Flt pos ,Bool now){slidebar[1].scrollTo (pos ,now); return T;}
Region& Region::scrollFitY(Flt min,Flt max,Bool now){slidebar[1].scrollFit(min,max,now); return T;}
scrollX would use slidebar[0]
4. I get some money
just kidding
the ones that you mentioned are the main reasons
5. I'm checking this (Tube + Box shapes work ok, only Ball seems to have some problems)
but it works ok on real models (for example human mesh in the SDK has maps created from normal map only, no bump map was used)
I'll check why Ball preview displays incorrect results.
