Description

While panning the canvas (with MMB+drag or Space+drag), add support for locking to the X or Y axis with the Shift modifier key held down.

If the viewport is tilted (with Alt+MMB drag or Alt+Space+LMB drag), it should remain aligned with the X and Y axes of the viewport not the tilted document.

Contributor guide

Research direction
Investigate the panning implementation in the viewport code. Add support for Shift key modifier to lock panning to X or Y axis. Ensure that when the viewport is tilted, the lock axes align with the viewport axes (not the document axes). Look at how other modifier keys (like Alt for tilting) are handled.
