Dragging element using property grid should progressively move element,

[mrvux]

When using left click to move an element on the scene as clicking on number and dragging :

Scene view only updates when we end dragging (release left button), so it makes the feature not really of any use (since we have no visual feedback until we complete the action).

Process should be:

• Left click -> Begin edit value
• While holding -> Update scene view so we can see progress of action
• Release left click -> Push action to undo stack

Thanks
