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.

Installation and Development describe native/windows-x64/freetype.dll,
how cl-ft2 finds it, what the build lacks and how to rebuild and check
it. Bitmaps have HEIGHT, not ROWS, and the examples whose results
depended on an earlier page's size now set it, so each gives what the
page shows; the vertical advance at 32 px is 32. The strike error's
hint names FACE-SIZE.
