[PD] GEM luminance

[chris clepper]

hi

this will be much easier in the near future on OSX (which is the 
platform you're using right?).  there are a couple of issues holding 
up YUV development at the moment, but once those are cleared up it 
won't take long to implement true hsv and luma/chroma keying etc.

ps - if anyone knows how to retrieve fourCC codes from a quicktime 
.mov file please email me at once ;)
