Mouse events on 2D pictures should have an event data node for mouse information

[altenbach]

A very common task when operating with 2D pictures are mouse down/move events where we are interested which pixel was just clicked. While there is an event data node for the clicked coordinates these are relative to the front panel and translating them into image pixel coordinates is a chore and requires jumping through flaming hoops tweaks. (i.e. label yes/no? zoom factor? etc.)

However, there is a "Mouse" property for 2D images that has all the information directly in pixel coordinates and mouse button states. Currently, we need to read that property inside the mouse event to easily get the information we always (always!!!) want in such an event!

It would be cleaner if mouse events on pictures would output these mouse properties directly as an additional event data node.

Two clear advantages:

• Cleaner code for those who know how to work with this property.
• Stop sending newbies on a snipe hunt trying to figure out how to translate the current "coords" event data node into something useful for the intended task.

Here is an example where this idea would have helped

Here's a picture for the graphical thinkers!
