Comment 5 for bug 1748174

In short how the function could work:
1) Hold down a hotkey
2) Move your mouse to pan the schematic or board layout

Additional:
*) Hotkey should be assignable
*) The mouse cursor remains stationary on your screen when you pan
*) Be able to use the Scroll wheel to zoom when you pan

This Reduces unnecessary mouse movements, and makes navigation and dragging components more pleasant and efficient. Mouse cursor can remain at the center of your screen, this is where you want it to be. (not forced to center of course)
