* Fixes listener not getting removed

* fix canvas sprite texture change

* found it!

* TilingSprite tint fix

* clean tilingsprite

* Fix Sprite.containsPoint edge handling

* Fix TilingSprite.containsPoint edge handling

* Use `*._texture.*` directly in Sprite.js

It could offer a bit little performance gains.
And  read texture via `_texture` is a common way/style in  PIXI.js

* Update CanvasTinter.js

* Update DisplacementFilter.js

* Update Graphics.js

Reason:
* Do similar things in similar way :  compute left / top , then add width/height .
* A very very very very (...* 1000000) bit little performance improvement :  one `-` & one `*` become one `+`.
* fix some words in document.

* Do check as same as `calculateVertices`

I already ask a question about this  https://github.com/pixijs/pixi.js/issues/3408  , but no one reply .
I think opening PR is better than asking question.

* Ensure `calculateTrimmedVertices` could run first

When first call `calculateTrimmedVertices` , it should ignore _transformID & _textureID

* Update Sprite.js

* Change names of private  temporary variables.

* Update Sprite.js

* Update Sprite.js

* Remove trailing-spaces

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 get/set width/height method , we don't need use  `this.texture` .

We could use `this._texture.X`to instead of`this.texture.X` , and it could offer a bit little performance gains.
