Lubosz Sarnecki 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

Nicolas Dufresne d576a71e9a gloverlaycompositor: Add shader to convert BGRA/ARGB -> RGBA
Depending on the bytes order we will get BGRA (little) and ARGB (big)
from the composition overlay buffer while our GL code expects RGBA. Add
a fragment shader that do this conversion.

Matthew Waters 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.

Sebastian Dröge 260104e485 glupload: Remove debug output from gst_gl_upload_transform_caps()
We can't know if the GstGLUpload type is initialized at this point already,
and thus our debug category might not be initialized yet... and cause an
assertion here.

As we don't print debug output for any of the other transform functions, let's
defer this problem for now.

Nicolas Dufresne b817307165 glcolorconvert-test: Test notify function for setup_wrapped
gst_gl_memory_setup_wrapped() now takes a destroy notify function. This
destroy notify is called to track the memory life time, hence will
notify each time a memory get destroyed. This test check that the
callback count is correct.

Adds an GST_VIDEO_OVERLAY_COMPOSITION_META_API_TYPE query to glupload
and glimagesink.  Detects the query from the downstream elements, so
it is executed only when downstream supports the overlay API.

This makes pipelines with textoverlay ! glupload ! gldownload ! xvimagesink possible.
Uses allocation meta struct for passing the window size upstream.
