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

notes from the readme:
notes:
- 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
http://www.poynton.com/notes/colour_and_gamma/ColorFAQ.html#RTFToC30
- please note that colorspace switching between objects is handled
automatically by GEM unless specifically stated (ie. by [pix_yuv],
[pix_rgba], [pix_grey])
enjoy!
