Subject: Bug 801: Split GraphUI's TextureButton: TextureSeqButton (Base) and
it's derivations ImageSeqButton + GLEventListenerButton + MediaPlayerButton
Split GraphUI's TextureButton to TextureSeqButton (Base) and it's derivations:
- ImageSeqButton
- displays an ImageSequence
- GLEventListenerButton
- displays any GLEventListener as rendered into FBO as an ImageSequence
- MediaPlayerButton
- displays movies
- Added public ImageSequence impl. TextureSequence,
was private SingleTextureSeqFrame.
- Demo GPUUISceneGLListener0A shows:
- MediaPlayerButton w/ Big Buck Bunny film
- GLEventListenerButton w/ GearsES2
- ImageSeqButton w/ 2 textures (pressed/released)
