Destroy texture working

Fixed masking

Fixed graphics

Moved validate context

Rename it all to systems!

Big refactor

Texture / render textures working ...

Also created global uniformGroup
Broke up webGL to projection / renderTexture manager
I’m on to something here! Almost there..

More updates added the mini-runner

Sag / image / canvas all in! ...

Base texture replaced..

More texture / framebuffer stuffs

Texture rig and some renaming

Texture stuff working cubes + two deee

Pass one

Little improve: Don't query `currentState` again (#3764)

* Fix `the fault after merge`

* Remove duplicate comment

* Update Filter.js

* Update Filter.js

Pass `currentState` to filter.apply() (#3421) ...

* Pass ```currentState``` to filter.apply()

see https://github.com/pixijs/pixi.js/issues/3317 

If  pass ```currentState``` to filter.apply() , users could get more informations  (e.g. get current sprite by ```currentSprite = currentState.target```).
It's very useful when users create custom filters.

And the ```currentState``` is the last argument , and pass it won't break any filter already existed.

So I think this PR is safe and useful.

* Update annotation about currentState in Filter.js

* Use eslint-disable-line

* Update FilterManager.js

* Update Filter.js

[v4.4] Revert "Fix #3609 , about `filterClamp` & `filterArea` (#3626)" (#3760) ...

* Revert "Fix #3609 , about `filterClamp` & `filterArea`  (#3626)"

The real fix is to exclude "filterClamp" from uniformData
That fixes outlineFilter and glowFilter

* added a test, so finscn wont break it again ;)

First pass uniform groups

User can decide whether auto-set the projection (#3612) ...

* User can decide whether  auto-set the projection

`bindShader` always  set the projection matrix  automatically . in most case ,  that's OK.

But When I create some new renderer of PIXI ,  sometimes it would make some problems.
e.g.
* shader no projectionMatrix
* shader need use a custom projectionMatrix (not  _activeRenderTarget's)
* shader use a cached array (don't want to call toArray every time)

So I add a new argument to `bindShader` , and the default value is true, so  it would break any current code of PIXI

.

* Update WebGLRenderer.js

Fixed crash in WebGLState::push(). (#3652)

fixed lint warnings (#3726)

Merge branch 'master' into dev

filter slot #0 for textures (#3721)

Add an easy way to clear RenderTexture (#3647) ...

* Add a easy way to clear RenderTexture

In current PIXI, clear a RenderTexture is complex : 
```
renderer.bindRenderTexture(myRenderTexture);
renderer.clear();
// restore the previous renderTexture
renderer.bindRenderTexture();
```
And bind renderTexture is a high-cost operation . We shouldn't call it for cleaning render texture.

So I  add this method.
