toolkit: add FontChooser live-preview font picker#18
Merged
Conversation
The picker the Font interface (v0.20) unblocked — the long-deferred sibling of ColorChooser/FileChooser. A vertical list of named fonts, each rendered in its own font so the row doubles as a live size/style preview; clicking one selects it, applies it as the active font via SetFont, and fires OnChoose. Defaults to a three-scale ladder of the built-in bitmap font (Regular/Large/Extra Large) so an app gets a working font-size picker for free. 100% coverage.
