Fixes bitmapFont resolution test and linting warnings

Fixed crossOrigin explicitly defined on ImageResource

Removed sourceScale from spriteSheet calculations ...

- sourceScale was a proper used only by SVG textures. This can be moved
to the SVG Resource.
- modified tests to reflect change

Merge remote-tracking branch 'origin/next' into next

Unit tests ...

Fixed text unit test
Fixed cross origin unit test

Merge branch 'dev' into next

First merge

Disabled mesh test ...

Currently only works with webGL..

Fixed instance issue

Disabled plane tests ...

Planes require a webGL context to be created currently

Linting

Modify tests ...

Removed canvas tests
Removed a few others for elements that are not quite ready yet
Fixed the rest!

Measure Text API, expanded (#3921) ...

* Added TextStyle.measure function (Applies to https://github.com/pixijs/pixi.js/issues/3903).

* Moved measure function from TextStyle to Text and made static.

* Updated JSDocs.

* Updated JSDocs again.

* Updates based on suggestions by @bigtimebuddy in PR.

* Created PIXI.MeasuredText to capture all the information for measuring text.

* Fixes for ESLint

* Fixes for ESLint

* Added PIXI prefix to returning MeasuredText.

* Added import for MeasuredText in Text.js.

* Refactored MeasuredText to TextMetrics and moved `measure` function into it.

* Forgot to move Text.wordWrap to TextMetrics.wordWrap

* Further cleanup of TextMetrics.

* Fixes suggested by @bigtimebuddy

* Removed clone and equals from TextMetrics as they are unnecessary.

* Destructured references to TextMetrics instance in Text and privatized TextMetrics.wordWrap.

* Deprecates calculateFontProperties & getFontStyle

* Moved getFontStyle to TextMetrics

* Made toFontString method on TextStyle

* Cache calls made to context.measureText for individual characters

* Use a smaller (10x10) canvas for TextMetrics

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

Hot-fix for Ticker's destroy (#3904) ...

* Use a linked list approach to ticker listeners

* Oops fixes test

* Minor fixes

* Removes unnecessary destroy check

* Minor optimizations

* Adds memory clean-up to Ticker

Added public hit test method. (#3878)

Merge branch 'master' into dev

Further fix issue described in #3851 (#3877) ...

Prepare plugin support for objects with multiple BaseTextures (#3830) ...

* Add ability for Prepare plugin to upload the all textures for AnimatedSprites

* Add a new function to loop through all the textures of an AnimatedSprite and add them to the queue
* Moved Duplicate `findBaseTextures` function from WebGL & Canvas Prepare to Base prepare as static
* Moved all the `findObjectType` methods to their appropiate class as static methods for consistency

* Updated Comments to reflect "static" not "private" methods

* Added the findTexturesForAnimatedSprites logic to the standard findBasicTextures

This cleans up the need to worry about ordering the registration of hooks and only calls upload once

* Split the prepare.register function into 2 registerFindHook & registerUploadHook

* Some simple cleanup before the PR

* comment formatting

* removed dependenvy on `extras` from prepare

* Fix small comment issues with pull request

Removed the [optional] reference in the comments for both
new register methods.
Added a small example to the docs

* Add deprecation method

* Added Check before calling hooks and reformatted JSDoc

Lint wouldn't pass without the params in the JSDoc

* added `instanceof` check and fixed up the return true only if a texture is found

Small Texture Cache enhancements (#3789) ...

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

* Added tests related to texture cache contents.
