aa2b23fe39 videoaggregator: repect the result of find_best_format in the default update_caps 
We weren't using the result of find_best_format at all.

Also, move the find_best_format usage to the default update_caps() to make
sure that it is also overridable.

a68c8978a6 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.

87031b14cb 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

374cd2a570 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.

Olivier Crête
6edf8dbaa6 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.
