f3653a5e9c gleffects: fix gleffects fisheye shader compile error
On some embedded systems, sqrt() is not supported in the shader,
use the actual value of sqrt(2) instead.

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

0fe34bfc1d glsinkbin: add glcolorbalance element

5c4e724f70 glcolorbalance: create the shader if it doesn't exist in the render callback
Changing the properties may result in glcolorbalance moving from passthrough to
non-passthrough and we weren't creating the shader in that case.

3cf98f7e5e 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.

066f0dcda0 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!

8c02a47741 gleffects: fix shader compilation with legacy opengl

6961945110 glmemory: add gst_gl_memory_allocator_get_default
Add gst_gl_memory_allocator_get_default to get the default allocator based on
the opengl version. Allows us to stop hardcoding the PBO allocator which isn't
supported on gles2.

Fixes GL upload on iOS9 among other things.

a3ebe19d87 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.

2b7495bbc1 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.
