the problem then is... my next stage in the pipeline is probably an xrender
composite of the pixmap i drew the yuv video data to... and that's where things
break down as finding a driver and card where xrender actually accelerates
transforms is like finding hens teeth (yes i know of the r200 ati xrender
accel. my only r2xx card is retired now in an old laptop and i hold little hope
of that card handling 1920x1080 video blends and scales with xrender at a
decent speed along with other workload as even though it is a good step up from
software, it's not as huge a leap as i have found native gl to be).
