The core Node is now able to distinguish a backdrop node which
The region denotes an area which can be instantiated/represented by two points, the top-left and the bottom right and allows for detection of points or other regions which fall under it. This could be used to understand when a node is a part of a backdrop.
A Backdrop node is default of pale yellow colour and is of the same colour in the header and the bottom area representing the node. Backdrop node allows user resize by dragging on the mouse area at the edges and also allows text appearing below the header from the notes section in the attribute panel.
In standard MacOS keyboards the backspace key is referred to as the delete key. Supporting both backspace and delete keys for delete operation in the graph ensures consistency across the different key layouts across devices.

Is there a reason why we totally overwrite the internal inputs instead of using the ones from the parent class and adding "Font Size" to it?
With the current way, there's a lot of duplication and the "Node's Label" internal attribute is lost, which I think is a shame since we may want to name the backdrop itself, and not just use the "Comments" attribute. This would prevent having several backdrops named "Backdrop", "Backdrop2", "Backdrop3", and so on... if we want to name them. Similarly, the "Invalidation Message" is currently preserved although it has no impact anywhere so far.

Not directly related to this, but when a backdrop contains nodes, is there no way to remove the background only and not the background AND everything it contains? (that's a real question, not necessarily a change request)
