27bafd4b81 video-transition: Make smpte props children properties

6acee38459 smart-mixer: Move the videoconvert to after the mixer 
So that it tries to negotiate with alpha and the alpha channel is
dropped as late as possible in the pipeline.

The compositor is able to do video conversion internally in any case
so having a videoconvert before it is useless.

ffc11daa40 ges: Use assets to instantiate track elements/group 
And deprecate all GESTrackElement constructors, but the GESEffect one.
Those should **never** be created by users and should become internal
in the future.

Stop having docstring for the constructors that were internal.

1729104c2c video-transition: When using non crossfade effect use 'over' operations 
For smptealph element to work as expected the following compositing
element should mix with the default "over" operator, as described
in its documentation.

a7347ca8f7 WIP: ges: fix API export/import and 'inconsistent linkage' on MSVC 
Export GES library API in headers when we're building the
library itself, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

Fix up some missing config.h includes when building the lib which
is needed to get the export api define from config.h

3c7f488fc2 video-transition: Port to the new 'operator' API in compositor 
Now subclassing a ghostpad with an alpha property so that
we can multiply the alpha of the frame positioning meta
and the alpha of that pad, setting it on the compositor pad.

50865a4f37 video-transition: Make sure crossfade output never contains alpha 
Otherwise it would get mixed with lower layers, which is totally
unexpected.

8aa407ff27 video-mixer: Fix the way we release mixer pads 
We were using the actual mixer pad to release the smart mixer
pad, which seemed to be on purpose, but was not properly handle,
moreover, it is now forbiden to pass a pad not inside a GstElement
when releasing it.

Also properly remove ghost pads from Smart mixer, we were planly
failling at it.

eb48faf342 ges: transition: Make crossfade fade out at the same time as it fade in 
Until now fade out was just fading in the new clip, but this is not
correct and crossfade should at the same time fade out while fading
in.

a66e674649 Include class related section documentation in the gir file. 
g-ir-scanner includes section docs as class/interface docs if the section name is equal to the lowercase type name.
Since all the documentation is in section blocks, rename them to match the type names.
