Improvements to how and what is stored in the texture caches. (#3834) ...

* Improvements to how and what is stored in the texture caches.
Built upon the good work from https://github.com/pixijs/pixi.js/pull/3789
+ For Text, the base textures were in the BaseTextureCache, but textures weren't in the TextureCache. This has been fixed
+ Now able to tell the BaseTexture the origin of where the canvas being passed through has come from. ie. was it from the text class? was it from the graphic class? was it from caching as a bitmap? More information now to track where these canvases (canvii??) have been generated from
+ BaseTexture has addBaseTextureToCache and removeBaseTextureFromCache functions, to match regular Texture. Any adding or removing to the BaseTextureCache is now through these functions

! Breaking change. When you call Texture.fromTextureFromCache - it no longer automatically removes it's base texture from the base texture cache. Not sure how people feel about this

? I don't like lines 233 to 236 in Texture.js, and line 591 in BaseTexture.js - I don't see why they are there or why they are needed, but I chickened out on removing them!

* Renaming function to more generic names

* Adding deprecation layer

* Fixed trying to add texture to BaseTexture cache causing unit test fail

* Fixed reading from the wrong cache

* Able to remove textures and base textures from their caches via object instances
Added debug warning if trying to add a texture to a cache id that already exists
Added unit tests

* Default string for texture origin

* Different object creation style

* textureCacheId is now an array of potential entries

* textureCacheId changed to textureCacheIds

* Removed unneeded string creation

Documents events for DisplayObject, renderers, Texture and BaseTexture (#3922) ...

* Documents events for DisplayObject, renderers, Texture and BaseTexture

* Converts to single-line event syntax

* Adds mouse/touch/pointer events for DisplayObject, fixes typo, adds interactive and interactiveChildren

* Added missing params on touchcancel and pointercancel

* Better helper docs for DisplayObject and Container

* Fix lint

* Removes mixin doc for PIXI.interaction.interactiveTarget

* Added more explicit types for `originalEvent`

* Fixes lint issue

Removed lots of logs

Bunch o fixes

Destroy texture working

Refactored from texture

More updates added the mini-runner

Sag / image / canvas all in! ...

Base texture replaced..

Small Texture Cache enhancements (#3789) ...

* Textures track cache id and remove from cache in destroy.

* Added tests related to texture cache contents.

Fix preparation of destroyed items (#3802) ...

* Added isDestroyed to DisplayObject, BaseTexture. Don't prepare destroyed items.

* isDestroyed -> _destroyed, marked as private

Pass one

Add BaseTexture.from() & fix a bug of `Texture.from` (#3736) ...

* Add BaseTexture.from()

* Add BaseTexture.from().
* Support create BaseTexture from HTMLImageElement.
* Support  BaseTexture cache.

* Let `Texture.from(img)` support BaseTexture cache.

Dedupe BaseTexture dimension updating (#3680) ...

* dedupe update dimensions

* lint

Better respecting of the scale mode (#3678)

fixed settings not being respected (#3315) ...

Discovered that using this kind of code:

```const { MY_SETTING } from settings;```

means that changing settings properties has no effect as the objects
are being set before the user changes them.

Moves constants that are actually settings (#3298) ...

* Made const that are setting writable

* Moved more items to the settings

spelling

Dev texture states cacheing (#3201) ...

* minimal texture bounds pass 1

* cheeky opts

* tidy up code

* create empty textures

* added empty texture

* couple more tweaks

* fixed empty texture issue

* fixed tweaked so id's sit on glTexture

means it should work on multiple contexts

* tweaked unbound textures

* tidy up

* upped max textures to 4 for mobile!

also sending state to tiling sprite VAO

* removed _activeTetureLocation

* tweaked eslint

* make sure buffer is bound

* updates based on @englercj review points

- Added vertexCount back in as it still yields much faster results in
iOS
- Tidied old comments
- Replaced i++ with ++i

fixes #3159

use objects where we map render context ids

replace url extension regex; fixes #3059

clean up to be specific

Huge refactor to match a new shiny eslint file.

Fix issue when creating a BaseTexture with a 'null' source value, then using .loadSource() with an already-loaded IMG element. The 'loaded' event is never fired in that case and Texture objects are forever waiting for the 'loaded' event to be emitted

Better SVG support (#2614) ...

* 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

* Fixed brace-style.

* Added util tests.

* Rebased to latest dev. Added 'px' support.
