Each layer is supposed to reexport the parts of the previous layer that are part of its API. - In painting.dart, export from dart:ui all the Canvas-related APIs that make sense to be used at higher levels, e.g. PaintingStyle. - Delete painting/shadows.dart. It was dead code. - In rendering/object.dart, export all of painting.dart. - In widgets/basic.dart, export all of painting.dart and animation.dart. Some classes in animation/ are renamed to make this less disruptive and confusing to the namespace. - Split out Stocks back into an import model rather than a part model, so that it's easier to manage its dependencies on a per-file basis. - Move Ticker to scheduler library. - Remove as many redundant imports as possible now. - Some minor nit picking cleanup in various files.
