Add debug draw modes such as Overdraw to 2D

[Arnklit]

Describe the project you are working on

A 2D game in production

Describe the problem or limitation you are having in your project

Our 2D artists have asked for the ability to debug rendering with options such as Overdraw and seeing the bounds of each sprite.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Add debug rendering to the 2D views similar to options we have in 3D.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

The options could be added to the View menu or a dedicated menu. It would work very similarly to the debug options in 3D.

If this enhancement will not be used often, can it be worked around with a few lines of script?

This would not be used very often, but I don't think this could be worked around with a simple script, it would need to be added in the engine.

Is there a reason why this should be core and not an add-on in the asset library?

I'm not sure this could be added with an add-on as it would have to tie into the rendering.
