Fix DisplacementFilter when using multiple filters (#4560)

Removes default loadType from the spritesheetParser load options (#4573) ...

Assuming a loadType of Resource.LOAD_TYPE.IMAGE conflicts with the ability to load an image which can't be loaded via the <image> tag.  This happens in the case of loading a compressed image which should be handled by the XmlHttpRequest file loader as an array buffer type.  In the resource loader, there is already a lookup to determine the load type: https://github.com/englercj/resource-loader/blob/master/src/Resource.js#L126
In the case of a binary image asset, the spritesheetParser's loadType stomps on a dynamic lookup based on filetype.

Cleans up documentation to remove JSDoc globals (#4542)

Fix bug #4467 : `scale` of ParticleContainer (#4511)

Canvas mesh alpha. Fix for #4534 (#4535)

`trim` shader's source when check precision (#4510) ...

Some users like add `one blank line` before & after the source code.
if no trim , `substring(0, 9)` can't work correct.

Fixes #4504 (#4508) ...

Documentation specifies incorrect default value for `autoResize` param to constructor of `ParticleContainer`. #4504

version of pixi-gl-core, renderer resets vao correctly. (#4462)

Region parameter for Renderer.generateTexture() (#4477) ...

* Added region param to generateTexture

* Call getLocalBounds() only when needed

* Updates the documentation for region parameter

removed @private from setTargetElement (#4469) ...

* removed @private from setTargetElement

this is a public method.

* Fixes linting error

Update docs of ParticleContainer (#4465)

Fix bug for adding extra blank ahead of the first line with word wrap (#4421)

Clear some properties in `ParticleBuffer.destroy()`. (#4407) ...

* Clear some properties in `destroy`

* Update ParticleShader.js

The ` vec2 v = aVertexPosition;` is needless , 
the  `v` is a new vec2 , use `aVertexPosition` will puzzle users (the people that read the code).

The  ` if (color.a == 0.0) discard;` will take unexpected result.

* Update ParticleBuffer.js

* cosmetic
