Fix #3794 (#3795) ...

Also add unit test for it and improve tests.

Uncomment & fix failing test from #3535. (#3638) ...

Resolves #3419 and #3628.

I just saw #3628 after I started working on this and I opened another PR (wrong) about the same bug #3628 looks good to me but adds an extra property, which I personally tend to dislike. This might have some side effects for cases that are untested, but I thought it's worth opening as an alternative to #3628.

Fix cursors not working as expected in nested interactive objects (#3704) ...

* Changed pointerout to pointerleave.

* Add comment about pointerleave event.

* Fixed cursor changes being mishandled.

Cursor changes should not be attempted if it just just the default
value.

* Fix #3689

* Make change from #3703

* Changed pointerout to pointerleave in tests.

InteractionManager Tests - Remove events (#3706) ...

* check for correct removal of events

* fix per test expectation

Reworked cursor handling to expand cursor options. (#3331) ...

* Enhanced mixins, replaced cursor handling with more features.

* Cleanup and fixes to interactive classes.

Mouse over/out/move was not being handled properly, and didn't work as a
result.

* Fixed inversion of flag checking logic.

* Added tests for interaction events and cursors.

* Removed now unused variables

Variables were private and readonly, so removal should not be a problem.

* Fix #3662

Needed better tracking of if events should have default prevented.

Merge pull request #3617 from themoonrat/event-types-doc ...

Marks the interaction events as being of the type PIXI.interaction.InteractionData

Mask/Fill interaction tests + fix (#3615) ...

* added expectations

* specify hitArea

* change expectation

* added filterArea expectation

* heed hitArea when mask present

* typo

* removed filterArea from interaction

Rebasing on dev to get MockPointer changes for #3375 (#3546) ...

* Fix issue #2662 Added a touch counter instead of flag to ensure the correct touch count

* See #2662 --- bending to the will of eslint

* See #2662 --- Added _touchCount to interactiveTarget.js, and removed an extraneous line in InteractionManager.js

* Removed an unnecessary check for _touchCount === undefined, since the mixin for interactiveTarget will always set this

* Fix issue #2662 Added a touch counter instead of flag to ensure the correct touch count

* See #2662 --- bending to the will of eslint

* See #2662 --- Added _touchCount to interactiveTarget.js, and removed an extraneous line in InteractionManager.js

* Removed an unnecessary check for _touchCount === undefined, since the mixin for interactiveTarget will always set this

* Adding cancel events to interaction manager

* Refactoring InteractionManager to normalize all events to PointerEvents. Also updated InteractiveTarget to handle multiple touch or pointer events by recording pointerId for all tracked events, rather than just counting events. Finally, InteractionManager now updates on all tracked events, rather than just mouse events, so it should send move events when UI objects move underneath any held event, not just the mouse

* Typo: mouse is not a function

* InteractionManager normalizeToPointerData now returns an array of normalized events for TouchEvents with multiple changedtouches

* Typo: no such thing as onPointerStart

* Fixing some more typos: trying to read the pointerId of un-normalized events

* Typos: un-normalized events don't have a pointerType

* Added identifier property to InteractionData, and got rid of some typos---trying to read pointerId from un-normalized events

* Forgot to bind onPointerCancel

* Refactoring interactiveTarget.js a bit, so that over, left down and right down are pointer properties, not mouse properties.

* Forgot an export default

* Changed the mixin pattern for Pixi.interaction.interactiveTarget, so that this is bound correctly, so that DisplayObjects can each get a unique object for tracking pointers

* Fixed some typos, moved interactiveTarget back to being an object, and released InteractionData after touch up/cancelled events

* Small fixed

* Safari compatibility

* hasOwnProperty fix

* Safer to use a string for mouse pointer than a number

* InteractionManager should now handle native DOM pointer events with pointerType mouse or touch by emitting mouse and touch events, respectively

* InteractionManager test now respects the refactored spec for InteractionManager

* Pointer events exclusive

* String.startsWith is not available in all browsers esp. older version of Safari. As it's just used in one place we can use a RegExp here too

* Moving from regex, slightly faster

* See #3149 --- Add support for touchcancel and pointercancel (#3375)

Marks the interaction event as being of the type PIXI.interaction.InteractionData in jsdocs

Improved documentation ...

Class member documentation improved via removal of unnecessary @memberofs - more members now show up in the docs.
Class getter/setter documentation improved using technique above, and also by removing documentation for setters. Documentation was only showing the setter docs, whereas the getter is where the important information is. JSDoc maintainers themselves recommend just doccing the getter jsdoc3/jsdoc#973
Documented a few classes to let devs know that they are automatically created by PIXI and added to renderer.plugins, like interactionManager and prepare
