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.
font-glyph-id, glyph-text-index, the outline cache, map-layout-glyphs in
the raster backend, glyph-region and glyph-image-offset; line-box,
line-content and run-box in place of line and run edges; and
map-layout-fields for distance fields.
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.
