Follow cl-textrender 03ab0f6: no global nickname textrender
The package cl-textrender has no global nickname any more. The
examples run in a package that gives it the local nickname tr, which
Home and Getting Started show, and prose names its symbols in full.
Follow cl-textrender 08f8561: faces, what fonts keep, and :WRAP NIL
Fonts describes faces, FACE-FONT, the fonts and faces freed once nothing
holds them, DESTROY-FACE, and FACE-CACHE and FONT-CACHE. The outlines,
rasterizer images and atlases are kept with the faces and fonts they come
from: CACHED-OUTLINE and CACHED-QUADRATICS take the font, the rasterizer
and the atlases need no releasing, and FONT-ATLAS and FACE-ATLAS give a
font's or face's pages. Laying Out Text and Typography describe :WRAP
NIL and lines cut short, and the references, Errors, Threads and
Lifetimes and the recipes follow.
Guides to fonts, layout, styled text and fallback, typography, vertical
text, coordinates, carets and selection, glyph outlines and the three
optional systems; recipes; a full API reference for every exported
symbol; errors, threads and lifetimes, the layout pipeline, limitations,
and platforms and testing.
