Fixes #4742 (#4743)

Pedantic spelling fixes (#4797)

Adds a caching layer to generateSyncUniforms (#4792)

Clean up of sprite helper functions (#4775) ...

* Clean up of sprite helper functions

* Full deprecated Sprite.from* and Texture.from* methods

Added resolution check in Texture.from (#4774)

Allow any object to be a stencil mask. (#4776)

Adds fullScreen (#4722)

Bugfix/masking whilst rendering to a render texture (#4739)

Mesh and Texture fixes (#4721)

Adds premultiplyAlpha option to ImageResource (#4729)

Re-adds missing blendFuncSeparate from StateSystem (#4728)

[next] mask alpha fix (#4725)

Adds defaults uniform names to Filter (#4714)

Replaces PREFER_WEBGL_2 and options.legacy with ENV and PREFER_ENV (#4718)

Fixes optimization for buffer upload (#4716)

Bugfix/fromBuffer (#4713) ...

* Fixed up fromBuffer

* Lint

* Options can now be passed to from methods

Full power to all!
Recommended defaults are used for buffer texture creation., but can be
overridden if required.

Fixes resolution issue with filters (#4715)

Reorganize the core module to be flatter, rename WebGLSystem to System (#4707)

Support v4 filters as legacy in v5 (#4703)

Set globals in the correct place (#4700) ...

* Set globals in the correct place

* Fixed lint issue

First pass at tidying up shader (#4688) ...

* First pass at tidying up shader

- reduced GLShader to be a storage object
- also GLShader renamed to GLProgram as it is attached to programs
- This above two points bring it in line with GLTexture and GLBuffer
- Now shader inspection only happens once instead of twice!
- Removed unused classes
- moved precision check to program

* Fixes linting

* tidy up of GLProgram

* Set type to be object

Fixed up resolution issue with RenderTexture (#4695)

Feature/filters (#4687) ...

* Done
- filters working
- nested filters working
- Less GPU calls than v4
- Now passing destination and source frames to shader to calculate verbs
- ONLY Color Matrix Filter working
- Filter Area is now transformed (like hit area, much more useful!)
- Less code :D

Todo
- Apply Filter no complete
- Multiple filters not. Complete
- Refactor other filters

Optimisations
- need to pool the FilterStates

* Smarter check to eliminate needles enabling of stencil

* - Quad draws with triangle strip
- multiple filters now working

* Fixed up resolution

Not only does resolution now work - but any texture pass can be ANY
resolution and it works like a champ!

* Moved docs removed a needless comment

* More optimisations

- Added caching layer to viewport
- renamed getRenderTarget -> getFilterTexture
- added active state to filter for easy access
- fixed and optimised blur filter at least 66% less gpu calls required
now :)

* Fix up alpha filter

* Fixed up all bundled filters!

* Filter clamp added to Displacement filter

* Fixed lint fail

* Fixed up use of ba instead of zw in shader

Also added defaultFilter vert

* Added doc to state in filter

* space..

* Added pooling and a few docs bits

* more tweaks

fixed blur Y filter bug
Fixed default filter frag bug
Set default padding to 0

* Removed the slice from filters #3639

* Added auto fit back in

We now Loop through filters to find appropriate padding / autoFit /
resolution rather than just checking first filter.

Also clamped blur in vertex shader so that it does not bleed
transparency around its edges

* Update eslint package

this seemed to fix it last time..

[next] Particles fix (#4600)

Fixes Garbage Collector system (#4593)

[next] Math `copy` inconsistencies (#4595) ...

* copy-from and copy-to inconsistency

* faster copyFrom for ObservablePoint

* deprecations

* Fixes deprecations docs

Windows tests are failing (#4589)

Bugfix/frame buffer textures (#4578) ...

* Fixes issue with frame buffers if depthTexture or colour texture are auto generated

Easy fix, we forgot to update the texture constructors to use the new
resource / object format.

* Lint fix, oops

Fixing mipmaps and renderTexture (#4559)
