...me too :-\  But we'll see...I'm wondering if it's a "how floats are 
dealt with differently on x86 vs ppc"-kinda thing, but haven't checked 
it out much...

...uh, I've already started to work on a gridflow to gem imageStruct 
thing, in a similar manner as pdp2gem...but nothing to get too excited 
about yet...in part I think that the slowness of gridflow in osx atm 
may be due to the way it's just drawing to the window instead of using 
the faster path...using CGContextDrawImage() isn't normally used for 
video redraws...
