Update of /cvsroot/pure-data/externals/gem2pdp
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv5559

Modified Files:
	README help-pdp2gem.pd 
Log Message:
added colorspace message which allows us to select the destination colorspace (YUV, RGB/BGR, RGBA/BGRA); now uses GemPixUtils color conversions to centralize the code

  gemp2pdp : GEM to PDP bridge
***************

+ 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])
