KiteVideoFrameCost

The measured CPU cost of KiteVideo's software path, per PUBLISHED frame: the conversion to RGBA plus the image build, on the renderer's worker thread, in nanoseconds.

What this is not: it is not the draw cost (Compose draws on its own schedule), not a GPU number, and not a device claim when it was measured on an emulator. Failed and superseded frames contribute no sample, so the average is the average of frames a viewer could have seen. These measured numbers replace the ones that were assumed before; real hardware re-takes them before any device claim.
