The API index lists face-size-designator, transform-matrix,
transform-delta, outline-coordinate and bitmap-size, and Sizes and
transforms, Glyph objects and strokers and Outlines name each where
they describe its values.

Errors lists the new type-errors, an axis tag that is not four
characters and a render-outline box beyond 2^23 pixels, and quotes the
report SBCL now gives for an argument that fails its declared type.
Font variations says that an axis tag of another length is a
type-error, and Outlines gives render-outline's limits.
Follow cl-ft2 e574516: the argument types are exported
The API index lists the twelve types cl-ft2 now exports, and the page
of each says which values make it up: font-source on Library and faces,
encoding and character-or-code on Character maps, hinting-target and
kerning-mode on Glyphs and metrics, render-mode, pixel-mode and
pixel-data on Rendering and bitmaps, line-cap, line-join and
stroke-border on Glyph objects and strokers, and fill-rule on Outlines.

Outlines describes OUTLINE, MAKE-OUTLINE and its checks, the tags,
OUTLINE-CONTROL-BOX, RENDER-OUTLINE and STROKE-OUTLINE, with examples
run against the code. Strokers, Rendering and bitmaps, Errors, Core
concepts, the FFI layer and the API index list them. The miter limit's
description had :miter-fixed and :miter-variable the wrong way round:
a fixed miter is beveled past the limit, a variable one clipped.
