GLMixer Code

oops.. last commit was incomplete !

Added support for FFMPEG version > 52.30 (svn) which now has to link with libsavcore.
Implemented the "ignore Alpha channel" mechanism to enable the reading of some rgba rawvideo files.
Improved management of sws filtering and scaling.

Yet again BUG FIX ; error in stop introduced by some recent changes, cleaning of code (drop option to use a thread for video refresh ; the idea is bad as it uses signal/slots to inform video source to update frame, which is not very robust between threads)

Clean up in management of option RenderingManager::blit_fbo_extension

bug fix on my former bug fix...

More BUG FIX in Video FIle : this time, I think its much better : 1) I do nothing special in the refresh timer (so there is no jump/ jerk of picture) BUT, 2) when the refresh timer start to be late on presentation time, it tells the Decoding thread to skip the next frame. This way, 1 or 2 frames later, the presentation time stamp to show is 1 frame later, so we can catch up. (+ compilation complain fixed in Rendering Manager XML).

bug fix again.... (culling in source and looping in video file)
