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)
Link to properties. Correct titles for examples. Document a few trivial cases. Keep lists in section file and docs/plugins/Makefile.am alphabetically ordered.

Use stream_time to synchronize the object properties.
Use running_time of the master pad to timestamp outgoing buffers.
Fix the initial segment event to extend an unknown amount of time.

When using gst_element_iterate_pads() one has to unref every pad
after usage.

Instead of a random number for the request pad id's,
use a counter.
Register the videomixerpad class from the element's class_init
where it's safer, and allows the docs generator to scan it.

Try using thaytans new mechanism to get extra classes into plugin
docs. Aparently works for the Eq. For VideoMixer the GObject stuff is
missing still.
