Class member documentation improved via removal of unnecessary @memberofs - more members now show up in the docs.
Class getter/setter documentation improved using technique above, and also by removing documentation for setters. Documentation was only showing the setter docs, whereas the getter is where the important information is. JSDoc maintainers themselves recommend just doccing the getter jsdoc3/jsdoc#973
Documented a few classes to let devs know that they are automatically created by PIXI and added to renderer.plugins, like interactionManager and prepare

In Texture , the `orig` is always exist after new Texture object . 

 If `orig` is not accessible , there will be a bug in the App.
The developers must fix it , not ignore and return `0`.

* Made const that are setting writable

* Moved more items to the settings

#3090: Putting this out here. After encountering #3085 this is what I found. Please feel free to revise as needed, as I admit my knowledge on the matter is limited. I hope it helps someone else.

2. texture now has an optional component

THIS IS THE PAIN

1. Rotated and trimmed textures are allowed
2. "full" textures use simple shader if they have WRAP_MODE.REPEAT
3. WRAP_MODE.REPEAT is forced if that texture uploads in TilingSprite first time
4. TilingSprite now has tileTransform which applies to the "zero tile" like if its been a child

cleanup some export defaults

* Better SVG support

* Images are loaded using canvas which enables pre-scaled textures
* Scaling is done by providing an extra parameter `sourceScale` to the `fromImage` method
* Size of the original SVG source is checked with an extra XHR (necessary step for the canvas API to work)
* Supports data URI based SVG
