Requested feature.

Enable Ctrl+Shift+LeftClick Dragging to pan the remote view when using interaction modes other than ViewInteraction.

Should close #933

just noticed #741 is sort of the same as this?

Any reason for requiring both Ctrl and Shift to be pressed?

Anyway, thank you for adding this.

Hm, right I suppose it could just be Ctrl, since this is only when not using the pan tool (Ctrl clicking with pan tool performs a Pick Element). I'll update with that change.

@mattkdab I'm stumped why the cla-assistant doesn't recognize you. I'll approve this and merge.
