Bug 1021: Make OVR access vendor agnostic: Package 'com.jogamp.opengl.util.stereo' contains all public interfaces/classes
Renamed interfaces:
CustomRendererListener -> CustomGLEventListener
StereoRendererListener -> StereoGLEventListener
New vendor agnostic 'stuff' in com.jogamp.opengl.util.stereo:
1 - StereoDeviceFactory
To create a vendor specific StereoDeviceFactory instance,
which creates the StereoDevice.
2 - StereoDevice
For vendor specific implementation.
Can create StereoDeviceRenderer.
3 - StereoDeviceRenderer
For vendor specific implementation.
4 - StereoClientRenderer
Vendor agnostic client StereoGLEventListener renderer,
using a StereoDeviceRenderer.
Now supports multiple StereoGLEventListener, via add/remove.
- MovieSBSStereo demo-able via StereoDemo01
can show SBS 3D movies.
