- A lot of work to support new Intel hardware using media-driver as VA
- For non-x86 devices, VAAPI display can instantiate, through DRM,
with no PCI bus. This enables the usage of libva-v4l2-request

- Layer priority is now fully automatic and they should be moved with

now deprecated.
- Added a ges_timeline_element_get_layer_priority so we can simply get
all information about GESTimelineElement position in the timeline
- GESVideoSource now auto orientates the images if it is defined in a
meta (overridable).
- Added some PyGObject overrides to make the API more pythonic
- The threading model has been made more explicit with safe guard to
make sure not thread safe APIs are not used from the wrong threads.
It is also now possible to properly handle in what thread the API
should be used.
- Optimized GESClip and GESTrackElement creation
- Added a way to compile out the old, unused and deprecated
- Re implemented the timeline editing API making it faster and making
the code much more maintainable
- Simplified usage of nlecomposition outside GES by removing quirks in
it API usage and removing the need to treat it specially from an
application perspective.
- ges-launch-1.0:
- Added support to add titles to the timeline
- Enhance the help auto generating it from the code
- Deprecate ges_timeline_load_from_uri as loading the timeline should
be done through a project now
