RoQ decoder: Work on RGBA-data interenally instead of YUV420-data (#250)
* RoQ decoder: Work on RGBA-data interenally instead of YUV420-data This fixes color-smearing artifacts on movement (caused by uneven motion vectors not being correctly applicable on half-resolution UV-buffers) and makes RoQ-video directly uploadable as texture. YUV-to-RGB-conversion is now done only when receiving new codebooks in the RoQ stream, which is a lot less data to be RGB-converted per-frame. * RoQ decoder: C89-compliant variable declarations * RoQ decoder: more consistent indentation
