Add options for dragging the canvas around

[MarcGoekce]

When switching often between draw.io and the browser, my brain gets confused with left-right mouse button to drag the canvas around.

A great option could be to add something similar:

Drag canvas button

Options for draging the canvas around are:

• ctrl , alt , etc...
• right mouse button
• middle mouse button
• none (left mouse button)

Do I understand correctly that the missing feature is right click to drag the object?

The other options should already be present.

This would be a little more complicated since the library which I heavily rely on does not support right click as far as I know. But it is definitely doable :)
