GLMediaPlayer enhancements: State, Camera options, detect and act on orientation change (flipped), API-doc,

- State
  - Fix state transition (initGL() error)

- Camera options
  - options uses ';' as query separator
  - don't use 'default' options, driver should know

- Detect and act on orientation change (flipped)
  - ffmpeg impl detects if flipped changes and triggers a SIZE update event.
    This allows application to react, i.e. re-init GL and use new TextureCoord's.
    Test: Works well on Windows w/ rawvideo dshow camera driver/codec.

- API-doc
  - TexSeqEventListener/GLMediaEventListener usage / constraints (GL, ..)
  - State transition fix
