Since MatN is working on an update for wikipedia for CinelerraGG, I noticed the inclusion of Adam's HV update as stated here:  "Bug fixes for running on a 4K monitor. Support for odd frame sizes in OpenGL. CR3 file format. Automatic histogram value."

I can look at the changes and with some help from Andrew/Andras might be able to incorporate any simple improvements in our version.  Initial fuzzy observation:

1) Bug fixes for running on a 4K monitor -- not needed as the 4K monitor development was done independently here and there is no correlation and no bugs have been reported.
2) Support for odd frame sizes in OpenGL -- probably not needed as a lot of work to accommodate OpenGL AND odd frame size has been done here over time.  But I do not know how to check this.
3) CR3 file format support -- not sure about this.  Does ffmpeg support CR3?
4) Automatic histogram value -- this should not be difficult to check to see if needed and merge in.
