Description:
This is an enhancement request for Draw.
Panning is a basic documentation browsing function.
To me, it as important as scrolling and zooming.

Those two functions (scrolling and zooming) do not require to select a dedicated tool in order to work. With the Select tool active, as soon as the mouse cursor is in the viewing area of the document, they just plain work: the [scroll wheel] scrolls the document, and Ctrl+[scroll wheel] will zoom in/out.

However, the same cannot be said of the panning function.
To be able to pan, the "Zoom & Pan" tool needs to be active and one will then use Shift+[middle mouse button].

It would be much better to be able to pan just using the [middle mouse button] on its own (or possibly along with the Shift key) when the cursor is in the document viewing area, in Select mode.
Various other programs work this way I believe.

Steps to Reproduce:
Activate the Select tool.
Try to pan using the middle mouse button.

Actual Results:  
Panning does not work.

Expected Results:
Panning works.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes
