Bug 1491: GLMediaPlayerImpl: Use a shared *GraphicsDevice for all compatible shared GLContext, removing resource restrictions
In a use case with hundreds of GLMediaPlayer instances,
this causes the application to bail out due to running out of resources.
+++
GLMediaPlayer exposes resource restrictions and locking related
with the created off-thread shared GLContext
due to its newly created NativeWindow *GraphicsDevice instance (on X11).
On the X11 platform, the *GraphicsDevice actually uses a native resource (X11 Display handle) and hence creating such device is costly and limited.
To operate an off-thread GLContext w/o actual X11 input handling,
it is *NOT* required to use a new instance.
+++
Further more, the device is using locking.
To operate an off-thread GLContext, it is *NOT* required to use locking on it
as it does not perform actual X11 input handling etc.
All operations are performed on the shared GL context.
+++
Solution is to create a shared non-locking device clone
compatible with the source.
A share counter shall determine that the last one actually gets destructed.
The usual ..
