ca15a26c11 glvideomixer: signal continuation in reset 
We want to iterate over all the pads, not just the first one.  Fix by returning
TRUE in the GstAggregatorPadForeachFunc.

Removes a GST_IS_GL_CONTEXT() assertion on shutdown with >2 inputs
using gst-launch.

f1323fb6df videoaggregator: don't do caps processing that is not overridable 
Allows the subclass to completely override the chosen src caps.

This is needed as videoaggregator generally has no idea exactly
what operation is being performed.

- Adds a fixate_caps vfunc for fixation
- Merges gst_video_aggregator_update_converters() into
  gst_videoaggregator_update_src_caps() as we need some of its info
  for proper caps handling.
- Pass the downstream caps to the update_caps vfunc

81a78449d5 glvideomixer: swap control binding proxy 
The ref_object and object parameters were the wrong way around.

For the typical use case where an application is setting a
GstControlBinding on the returned ghost pad:
1. our control binding would be removed when the new one was set
2. sync_values calls were not being forwarded from the internal
   pad to the ghost pad.

If an application attempts to perform other control binding
operations (get_* family of functions) on the internal pad, they
will also be forwarded to the ghost pad where a possible
GstControlBinding will provide the necessary values.

b05002776b glvideomixer: Add GstControlBinding proxy 
This is used to proxy GstControlBinding to the pad on the
parent object. This avoid having to sync the values in the proxy pad,
this is too early if you have a queue between the pad and the actual
aggregation operation.

fa6dbaeb6c glmixer: Implement GstVideoAggregator::find_best_format() 
Without this, we will fixate weird pixel-aspect-ratios like 1/2147483647. But
in the end, all the negotiation code in videoaggregator needs a big cleanup
and videoaggregator needs to get rid of the software-mixer specific things
everywhere.
