Disable autoPan for shape popup

[will-moore]

This fixes a minor bug where the image pans when drawing shapes because of the popup appearing for a new shape. The shape popup should never cause the image to Pan.
To test:

• Select to draw a Shape E.g. Polygon
• Click on the image near the top of the viewport to start drawing
• The shape popup will appear and track the Polygon as you draw it, but it should not cause the image to pan. NB: this was noticeably worse when using Shift-draw to draw freehand.
• Also, clicking to select existing shapes when they are close to the edge of the viewport should also not cause the image to pan.
• In multi-viewer mode, popups and tooltip should work properly on both viewers.

Works as expected. Ready to merge FMPOV
