Description:
As an excellent drawing software, intuitive panning gesture is a highly expected feature. I see such requests for 10 years, which asks for panning  (called "Shift" in Draw) while holding down the mid-mouse-button. However, holding down that button is usually finger-hurting. So here may I suggest a better solution:

Allow canvas panning while:
- Moving mouse, while holding down the space key, like we do in QGIS;
- Dragging with LButton, while holding the Ctrl key, like in Blender;
- Dragging with RButton, like in draw.io.

Luckily, no function conflicts with these behaviors for now. Ideal to implement.
