Changes uncovered by Altair 4

In https://github.com/altair-viz/altair/pull/1818 I begun the process of making Altair wrappers for Vega-Lite 4.0.0-beta.12. This introduced a couple test failures in examples due to properties that are no longer allowed by the schema.

To add back

• https://altair-viz.github.io/gallery/ridgeline_plot.html fails because bounds is no longer an allowed property of TopLevelUnitSpec.

  • Ham: this one we should add back.

• Any charts that use width or height in the view configuration break, because they are no longer allowed properties of ViewConfig

  • Ham: this one we should add back, perhaps as deprecated configs.

Need to decide whether we want to add these back

• https://altair-viz.github.io/gallery/anscombe_plot.html and several others fail because columns is no longer an allowed property of TopLevelUnitSpec.

• https://altair-viz.github.io/gallery/beckers_barley_trellis_plot.html fails because rangeStep is no longer an allowed property of Scale.

• Similarly, https://altair-viz.github.io/gallery/layered_chart_bar_mark.html fails because rangeStep is no longer an allowed property of ScaleConfig

This is the extent of the issues that came up in a first pass!

The current release of Altair uses Vega-Lite 4.0.2, so it’s possible that errors you see in Altair output won’t reproduce in the Vega editor (which I believe is at 4.4 at the moment)

Great! Already done in https://github.com/altair-viz/altair/commit/0ccd2e4a8c59f9fa5a1009ed4716bd6882187d01
