Follow cl-sdf d4f19ae and 2f0e1da: full domain types, a field's bounds
Errors shows the type-error SBCL now signals for a bad argument and lists each argument's declared type, and make-colored-edge's segment is checked by its type. The API reference, How It Works and Development say what the ftypes declare. A field's bounds are four double-floats, a rectangle unless padding took them beyond ±1e36.
The requirements, the test command and CI name SBCL alone, numbers in
messages are described in SBCL's syntax, and what queries allocate is
no longer qualified with "on SBCL".
Coordinate ranges, colored contours in place of :COLORED-CONTOURS, the
angle threshold's meaning, INSIDE-P on open contours, exact numbers in
messages, brief printing and query allocation. The channel distances
now scan every line, with timings measured again. cl-textrender's
FONT-GLYPH is FONT-GLYPH-ID.
Concepts, contours and fill rules, generating, reading and drawing
fields, edge coloring, error correction, distance queries, recipes,
API reference, errors, accuracy and performance, how it works, and
development.
