v-sync control

Abstractamcr:

couple things and maybe they have been suggested before but i would love to have v-sync on the controls and be able to assign a midi button to turn it on and off. Also for a loop toggle would be helpful.

UFFFD:

I don't think that has been suggested actually. what's the use case? just using it enable faster visual effects?

@UFFFD i find it really handy switching betteen vsync on and it off. some shadders behave so differently when vsync is off than when its on. Since i have discovered this (thanks to a question from @Jungle Boswick ) I have been finding myself toggling over to settings to click it on and off fairly often, which takes my eyes off the show a bit longer than is ideal. find myself doing it about 4-5 times a show over the course of 3 hours. would be super handy to have that be a button

No files, tests, or entry points are named. Start by locating the existing v-sync setting and the MIDI control-mapping path, then clarify whether the loop toggle is in scope; done means v-sync can be toggled from an assigned MIDI button without leaving the show.
