Feature Request: Option for "Mouse moves Viewport" panning with Mouse Lock

I've played OpenTTD, and I have found that I prefer "Mouse moves Viewport" panning much more than "Mouse moves Canvas" panning because your mouse can move in one motion, instead of going back and forth. Additionally, Mouse Lock keeps the cursor within bounds of the window, so there's no problem with your mouse leaving the window.

Basically, have an option to invert panning direction and/or activate pointer lock while panning.

(IMO the terms I used here, which are adapted from OpenTTD, explains it much more nicely than "Normal" and "Inverted")
