When iframes get inserted they create untracked elements, both on the dom and rrdom side.
Because they are untracked they generate negative numbers when fetching the id from mirror.
This creates a problem when comparing and fetching ids across mirrors.
This commit tries to get away from using negative ids as much as possible in rrdom's comparisons

Based on: https://github.com/rrweb-io/rrweb/pull/859#discussion_r846582146
* Add very basic webgl support
* document the default

* rr_dataURL no longer part of webgl snapshot
* ignore __diff_output__ from jest-image-snapshot
* Rename generic "Monorepo" to "RRWeb Monorepo"

* Remove blank dataURL
* reference original file not type defintion file
* update types
* rename code worspace
* update dependencies
* add spector to inspect webgl
* remove live server settings from code workspace

* Move pendingCanvasMutations to local object and fix if/else statement
* Always save pending mutations
* only use assert snapshot as it's clearer whats going on
* Ugly fix for now
* Making the tests more DRY
* flush at the end of each request animation frame
* Looks like the promise made this test more predictable
* add waitForRAF
* Make nested iframe recording robust no matter the test speed
* mute noisy error in test
* force a requestAnimationFrame
* Bundle events within one frame together as much as possible
WebGL events need to be bundled together as much as possible so they don't accidentally get split over multiple animation frames.
`newFrame: true` is used to indicate the start of an new animation frame in the recording, and that the event shouldn't be bundled with the previous events.
* Rename RafStamps
* Override event.delay
* cleanup
* Add tests for addDelay
* Add webgl e2e test
* Remove settimeout

* fix tests
* don't save null objects as WebGLVar
* group (de)serialized webgl variables by context
* Fix test
* fix tests
* bundle webgl mutations on request animation frame
Instead of fixing it on the replay side we buffer up webgl canvas mutations and wait for a new RAF to flush them. This allows us to remove `newFrame` from the events and simplify things a little
* Add canvas element to mutation observer file
* Add Canvas (Mutation) Manager
Allows you to do `record.freezePage()` and canvas events will get paused.
Based on https://github.com/rrweb-io/rrweb/pull/756#issuecomment-1007566907
* cleanup
* Make sure the correct </body> gets replaced

* Access unpatched getImageData
* Use is2DCanvasBlank only for 2d context
* create rrdom package
* test(rrdom): add unit tests for polyfill.ts
* fix(rrweb snapshot): type check errors
Errors are caused by the declaration similarity of @types/mocha and @types/jest if we install both of them in the whole project.
* Set tagNames to upper case by default
This mirrors the `Element.tagName` implementation:
```
For DOM trees which represent HTML documents, the returned tag name is always in the canonical upper-case form. For example, tagName called on a <div> element returns "DIV".
```
https://developer.mozilla.org/en-US/docs/Web/API/Element/tagName
* Add workspace file
* VSCode settings for rrdom tests
* Add basic test for RRDocument
* Only setup jest tests for rrdom

* fix: querySelectorAll returns nothing when querying elements with ids and classNames
* fix: error of unit test for Event polyfill
Since Event class is built in nodejs after v15.0.0
* add a dummy implementation of canvas
* add style element support
* add unit test for style element
