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

Fix `the fault after merge` (#3766) ...

* 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 ;)

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.

* Add `return this`

initial commit for ultimate renderer dimensions solution (#3657)

Fix docs and export issue, Filter is a class

Added legacy option to webGL renderer (#3630) ...

* Added legacy option to webGL renderer

Setting ```legacy``` to true now forces VertexArrayObjects and
MultiTexture Batching to be disabled. We also store the variable on the
renderer just incase we want to use it to force settings in anything
else.

also added a test

* remove WebGLTests as they don't work on server

* Added extra param to Application

* Adds WebGL test for legacy

* Better check for WebGL in tests

Better respecting of the scale mode (#3678)

FilterManager shaderCache reset as object (#3664) ...

The shaderCache is initially created as an object. When the Filter Manager gets destroyed, it should be reset to an empty object, not an array.
