yup:  just committed it to cvs, and also put a pre-compiled version on 
my ugly website:


notes from the readme:


- now allows you to select the colorspace that pdp's yv12 image format 
is converted to.  This means we can now request a YUV colorspace, which 
is computationally much faster than yv12 to RGB or RGBA (so much so 
that it is the default).  Colorspace can be indicated on object 
creation (ie. [pdp2gem RGB]) or by message (ie. [colorspace YUV<)

-  now uses standardized color conversions found in GemPixUtil.cpp, 
which includes altivec speedups!  These use formulae from 

- please note that colorspace switching between objects is handled 
automatically by GEM unless specifically stated (ie. by [pix_yuv], 
[pix_rgba], [pix_grey])
