Source selection GUI

Those toxes allows you yo nicely present a video feed (VideoViewer.tox) and build a selection / cut bar GUI system with Tallys & UMD (SourceSelector.tox).

SourceSelector is made for touchscreen system where the thumbnail of the source is used a button. Lef (red) zone is PGM, right (yellow) zone is PVW. The tox uses custom parameters.

The provided exemple toe is a simple 4ch video switcher GUI using a simple (dumb ;-) ) parameterexecute for logic that uses both toxes.

SourceSelector.tox and VideoViewer.tox require Style.tox for GUI colors definition.
