362785df88 videomixer: optimize blend code some more 
Use more efficient formula that uses less multiplies.
Reduce the amount of scalar code, use MMX to calculate the desired
alpha value.
Unroll and handle 2 pixels in one iteration for improved pairing.

0a0f7ecc16 videomixer: Use movzbl instead of movzxb for moving one byte to a l register 
For some reason latest gcc/binutils accept movzxb here while
movzbl would be correct and is the only thing accepted by older
gcc/binutils.

Fixes bug #604679.

Sebastian Dröge
061ededa36 videomixer: Add MMX implementations of the AYUV blending and color filling functions 
This provides a 20% speedup for blending and 100% for color filling.

The blending can probably be optimized even more.

66d3ac8fb7 videomixer: Dequeue current buffer on FLUSH_STOP and don't unref NULL buffers 
... NULL buffers shouldn't really happen anymore when popping the
buffer from GstCollectPads but better check for this and print a warning.

93089ef445 videomixer: The queued duration is a signed integer 
...and it will really be negative sometimes.

7418dee253 videomixer: Only pop buffers from collectpads after they're fully consumed 
This decreases latency and memory usage because new buffers are only
accepted by collectpads if there's no queued buffer.

b02949faeb videomixer: I420 mode: Add fast path for 0.0 and 1.0 alpha 
If the source alpha is 0.0, we take nothing.
If the source alpha is 1.0, we overwrite everything.

3c88249d48 videomixer: I420 blending : Fix main algorithm. 
When blending a source layer with an alpha of 'a' on top of another
destination layer we take the sum of:
* 'a' percent of the source layer
* (100 - 'a') percent of the destination layer (the remainder)

where it's safer, and allows the docs generator to scan it.
