Elias Naur b07d34354e text,widget/material: make font collections explicit ...

Before this change, package font implemented a global font registry,
with the usual problems of package global state.

This change deletes the global registry and introduces the text.Collection
type for representing a list of fonts and their faces. Collection exports
Lookup that finds the closest match and its face.

The existing FontRegistry is renamed to Cache to reflect its new limited
functionality: a cache of shapes and measurements on top of a Collection.

Then, material.NewTheme is changed to take a Collection and initialize
a Cache.

Updates gio#19 because multiple windows require a separate (writable) Cache per
window, while (read-only) Collections may be shared.
