GLMixer Code

Implementation of varying size picture queue : the number of frames in
the buffer between decoding thread and display loop is based on the size
of the file (e.g. 10% num frames total) and is adjusted depending on the
play speed (larger if playing faster to allow decoder to read faster
forward when speed is higher).

New implementation of VideoPicture and of the picture queue in
VideoFile:
Dynamic allocation of the queue to ensure the picture created is never
erazed or changed before it is dispayed.
This fix the long lasing bug with pictq and the read-write indices: the
VideoSource was displaing the frame AFTER (asynchronously) the pictq
read index was set, i.e sometimes too late and then jumping randomly in
the queue.

Tiny bug when no current source
