Observation about Stock Movie Player vs. "UserBackdrops"

Something I've found that is mildly interesting is that the "UserBackdrops" patch puts out a movie image that is a CIImage, with a LinearRGB color space, whereas the stock player is a CVPixelBuffer, with the "601" color space.

I haven't found any real difference in performance so far, but I haven't tried too much so far to see if one or the other works more efficiently when combined with other patches.

Interestingly, while I was looking at this, I also looked at the performance toll of rendering to a Billboard inside of a Render In Image, which converts the image to a QCImageBuffer, but produces no performance hit on my system.

That is all. No conclusions or big revelations.
