v68.0.0

This major release includes a breaking change in behavior for Bottom Sheet's shapes themer, a
variety of bug fixes, a new color themer for NavigationDrawer, and documentation for the Shape
theming system.

Breaking changes

Bottom Sheet's shape themer behavior has changed:

Bottom Sheet now maps the top 2 corners to the Large Component Shape category when the sheet isn't
in a full screen state. When the sheet is in full screen, we do not map it or shape it at all.

New features

NavigationDrawer now has a color themer.

Sliders now respect exclusive touches.

API changes

NavigationDrawer+ColorThemer

New extension.
