7f8e09523f 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.

e03e983e90 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

e3f53deb32 glcolorbalance: create the shader if it doesn't exist in the render callback

5ecc3413fd glvideoflip: incorporate the aspect ratio into the scale_x calculations 
1. Otherwise rotating the video will clip and show black bars due to
   gltransformation's implementation.
2. The other option of make gltransformation aspect-agnostic produces
   incorrect output with perspective transformations.

1fe2996b01 gltransformation: implement navigation events 
Reverses the transformation applied through the properties and forwards the
event.

The process for finding the coordinates on the video are as follows:
1. Convert the given pointer_x and pointer_y to model space at the near and far planes
2. Get the equation of the video plane
3. Find where the ray in 1 intersects the plane
4. Profit!
