Request: screen tearing on linux, need to allow VSYNC #1652

Not sure why but getting really bad tearing on my setup in TIC-80.

There used to be a "vsync" option in the config cart but I couldn't find it any more.

Someone suggested to me that it's to do with Xorg setup but I have games installed with perfect vsync, zero screen tearing.

It's especially noticeable when something is scrolling horizontally, the screen tears and the tear slowly moves up and then cycles. It's to the point that it can interfere with gameplay.

We could add a --vsync command-line option to enable VSYNC.

Added --vsync cmd option as well as VSYNC=true option to the config a13f380
