* record canvas mutations
close#60, #261
This patch implements the canvas mutation observer.
It consists of both the record and the replay side changes.
In the record side, we add a `recordCanvas` flag to indicate
whether to record canvas elements and the flag defaults to false.
Different from our other observers, the canvas observer was
disabled by default. Because some applications with heavy canvas
usage may emit a lot of data as canvas changed, especially the
scenarios that use a lot of `drawImage` API.
So the behavior should be audited by users and only record canvas
when the flag was set to true.
In the replay side, we add a `UNSAFE_replayCanvas` flag to indicate
whether to replay canvas mutations.
Similar to the `recordCanvas` flag, `UNSAFE_replayCanvas` defaults
to false. But unlike the record canvas implementation is stable and
safe, the replay canvas implementation is UNSAFE.
It's unsafe because we need to add `allow-scripts` to the replay
sandbox, which may cause some unexpected script execution. Currently,
users should be aware of this implementation detail and enable this
feature carefully.
* update canvas integration test
* part of #80, support mask input options
* close#188 enhance sampling options
Use a more general sampling strategy interface to describe the
configuration of sampling events collection.
Implemented mousmove, mouse interaction, scroll and input sampling
strategy.
According to @eoghanmurray's suggestion, we can support three
main scenarios:
1. record only
2. replay only
3. all in one
Since we have implemented the packer feature, which has a big
influence in bundle size, we provide another three bundles:
1. record and pack
2. replay and unpack
3. all in one with pack and unpack
* refactoring play, pause, resume, load style sheet to subscribe style code
* support live mode in state machine
* 1. upgrade @xstate/fsm
2. add toggle interact methods to the player
* introduce pako and add general packer interface
* add tests for packer
* use function API instead of class API for better tree shaking support
* refcatoring the rollup bundle config
* hack together stylesheet observer
* Add test coverage for insertRule/deleteRule on stylesheets
* Add new observers
* update patch based on changes to master
* Functioning event recording
* Remove print statements
* Fix ID usage and mark add vs remove
* Correct type
