Changes

Graphics: OpenGL 3.1 support (Order-independent transparency support is only avaliable available in OGL 4.5 or higher)

On [https://redream.io/posts/improving-audio-video-synchronization-multi-sync July 2018], inolen introduced a major change to redream's audio / video synchronization in version 1.2.3 by utilising utilizing a feature called, in his words, "Multi SyncMultiSync". This helps to prevent audible crackling, unexpected latency in audio and skipped or torn frames in video output. The solution does involve some added code complexity and memory bandwidth to handle the extra blits.
