* Update ScriptableContext, reduce warnings

* _parsed is unknown[]

* Add defaults

* static defaults.

* review update

* Not totally sure this is right , but since in core.adapters.js override is part of the dateadapter it seems logical it should be there. Should also fix #8369
* implemented feedback
* Declare the dataAdapter since it will be available at runtime if someone overrides it
* remove declaration. if this is giving problems in the future it might need te be added again

* Add indexAxis to CoreChartOptions
* Update types for indexAxis

* Make the raw data point available in scriptable context
* Rename variables
* Update samples

* Improve radial gradient sample

* Create a new hook to enable data decimation

The `beforeElementUpdate` hook can be used to decimate data. The chart
elements will not be created until after this hook has fired ensuring that
if decimation occurs, only the needed elements will be created.

* Address code review feedback

* Rename hook to beforeElementsUpdate

* Simplify parsing logic

* Add decimation plugin to the core

* Allow a dataset to specify a different data key

* Decimation plugin uses the dataKey feature

* Refactor the decimation plugin to support configurable algorithms

We define a new descriptor for the `data` key allowing the
plugin to be simpler.

* scatter tooltip should be point by default
* edited mode on better level and updated docs to be bit more clear

From what I understand, if we want to allow registering additional element options (see [here][1] for an example), then the element options need to be a top-level interface so that they can be used with TypeScript's [declaration merging][2].
