We can do everything with gles3 however gles2 restricts us not allowing

c766ca0381 glshaderelement: implement setting arbitrary uniforms
Currently float and int are supported by default. vec2, vec3, vec4
and mat4 are supported if graphene is used.  Of course if one wants
to set custom uniforms they can also be set using the create-shader
signal.

5efb855edd glupload: Use base class metadata copy function
This allow properly copying selected meta, like the composition
overlay. Note that output buffer need to be readable, but GlUpload
keeps a ref. For now, simply drop GlUpload ref after perform,
leaving that ref has no purpose. The method shall be removed
in the future.

6a58c684a7 gltransformation: implement pivot point for rotation and scale
https://bugzilla.gnome.org/show_bug.cgi?id=744763

Add a pivot vector for setting the origin of rotations and scales.

With the pivot point the rotation and scale operations can have
different origins. This adds the ability to rotate around different points.
Currently the default (0, 0) pivot point is possible,
a rotation around the center, and zooming into and out of the center.

With an pivot point this is optional.
I defined the following image coordinates for the pivot point:

	 (-1,1) ------------------------- (1,1)
		|			|
		|			|
		|			|
		|	  (0,0)		|
		|			|
		|			|
		|			|
	(-1,-1) ------------------------- (1,-1)

Example:

	Rotate the video at the bottom left corner

	gst-launch-1.0 videotestsrc \
			! gltransformation \
		 		scale-x=0.5 \
				scale-y=0.5 \
				rotation-z=25.0 \
				pivot-x=-1.0 \
				pivot-y=-1.0 \
			! glimagesink

The pivot-z option defines the pivot point in 3D space.
This only affects rotation, since we have no Z data to scale.
With this option a video can be rotated around a point in 3D space.

Example:

	Rotate around point behind the video:

    	gst-launch-1.0 videotestsrc \
			! gltransformation \
				rotation-x=10.0 \
				pivot-z=-4.0 \
			! glimagesink

dec64d9036 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.

f59948c5c0 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.

4cf2d84315 glupload: Forward composition meta even without params
When the sink does not know the window size (e.g not created yet)
it will not add any param to the the composition meta. This is no
reason not to forward this meta API. Fixes issue where it could not
attach until we resize the window.

052b0a1caf glimagesinkbin: Add allocation query for GstVideoOverlayComposition
Adds an GST_VIDEO_OVERLAY_COMPOSITION_META_API_TYPE query to glupload

it is executed only when downstream supports the overlay API.

This makes pipelines with textoverlay ! glupload ! gldownload ! xvimagesink possible.
