7b2ab7279f 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.

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

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!

09677a4d30 glimagesink: don't deadlock on resize
Performing any GL function marshalling off the GL thread with glimagesink's
render lock is prone to deadlocks between the GL thread and the non-GL thread.

What can happen is this:
1. non-GL thread attempts to function marshal to the GL thread.
2. while 1 is happening, the winsys gives an event (say resize)
3. This calls back into glimagesink which taks the render lock.
4. As the GL function marshalling is attempting to run on the GL
   and already has glimagesink's render lock locked.  This deadlocks
   as the threads are waiting for each other.

76a38dd66a glmemory: base classify and add the pbo memory on top
The base class is useful for having multiple backing memory types other
than the default.  e.g. IOSurface, EGLImage, dmabuf?

The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.

This also moves the format utility functions into their own file.
