Refine GLMediaPlayer/TextureSequence, add MovieCube demo, fix minor bug in Texture

- Add TextureSequence, base interface of GLMediaPlayer to genralize texture streams

- TextureSequence / GLMediaPlayer: Use inner classes for event and texture data

- getLastTexture() shall never return 'null', initialization of TextureSequence (initGLStream(..), etc)
  shall provide a TextureFrame w/ the stream's dimension.

- GLMediaPlayerImpl.createTexImageImpl() y-flip defaults to 'false'
  impl. shall define y-flip, if required.

- Added MovieCube demo

- Fix Texture: initialize aspectRation for 'wrapping' ctor
