Allow Signals to continue being sent when mouse is pressed

[MrJoshBowman]

I'm working on a game that allows for grid based selection where I want the user to be able to click and drag the mouse around a grid to select various squares and not just as a box selection.

Currently, from what I've been able to research, once a node is clicked and the event registered, no other events or signals can be sent until the mouse is released. The means that if I click inside one square and drag across to another, no mouse_exited() or mouse_entered() signal is sent until i release the mouse. This limitation is very frustrating, as there isn't even an option to switch this on or off as an option, and means that currently any dragging around a UI using simple signals has to be turned into something else needlessly complex.

I would very much appreciate the option for MouseButton events not to stop other signals from occurring.

this could be made possible with something like set_mouse_capture( ) [default: true] which retains the original way things are currently, but set to 'false' allows for the mouse to continue sending signals to other nodes as it moves over them while pressed.
