[PD] Gem: color to pix

[chris clepper]

Do you want to do something like add more red to an image?  pix_gain will
multiply each channel (R G B or Y U V) by a coefficient and pix_offset will
add to the channel.  You can also try the colorRGB object to modulate the
color value in hardware, but the coefficients are limited to 0..1.
