d9a96ac2ec compositor: Revert most of previous patch.
The calculation doesn't produce the same results.
Keep just the change to divide alpha by 255 instead of 256,
for slightly better accuracy

6a1f97cd50 compositor: Fix blending functions
Correctly calculate alpha in a few places by dividing by 255,
not 256.

Fix the argb and bgra blending functions to avoid an off-by-one
error in the calculations, so painting with alpha = 0xff doesn't
ever bleed through from behind

26d1a22e90 aggregator: Add a timeout parameter to ::aggregate()
When this is TRUE, we really have to produce output. This happens
in live mixing mode when we have to output something for the current
time, no matter if we have enough input or not.

Also provide a GstVideoBufferPool to upstream just in case.

8bf2acba1d videoaggregator: operate on caps rather than video info
Otherwise the CapsFeatures will be lost along with the possibility
of multiple output types and formats.
