Improved RGB→YUV conversion v2 (use MPEG range instead of full range)
Video-out plugins expect MPEG range Y'CbCr data (Y'=16..235, Cb,Cr=16..240).
RGB sources (still images and audio visualisation effects) need to be
converted first.
This patch fixes up the range calculations and corrects an off-by-one in the
range for Cb and Cr over commit 68fcd69fb3b6 (which was reverted due to API
change). It should also provide a little more accuracy: I've gone back to
the source (http://www.itu.int/rec/R-REC-BT.601/) for the conversion
information.
(We should use float or double here, but that would be an ABI change.)
