PR coming soon

[WillAyd]

This is probably tough to do in one pass. If you want to break up into a few PRs that should work too

[vaibhavhrt]

Yeah it will be nice. PR with large changes are hard to review and debug. I am kinda busy these days but I will get to it soon.

Whew it's a big one ~8k lines class. I will annotate all the @property methods on top of class first. The methods of the class are grouped using comments(eg. Rendering Methods, etc.), I will pick one group at a time in one PR.
