Fix grammar errors: missing words ("may not be available", "must be
passed to", "data is processed"), wrong articles ("an OpenType",
"a multi-band"), subject-verb disagreement ("operations...return"),
duplicated words ("can be used"), missing prepositions, and errant
periods.

Fix typos: "GDB" (was "GBD"), "chromatic_adaptation" (was
"chromatic_adaption"), "contiguous" (was "continuous"),
"counterclockwise" (was "counter clockwise"), "XYZ-transform" (was
"XYZ-transformed"), "included" (was "including"), "BGR;16" (was
"BGR 16"), missing closing parenthesis/quote.

Fix minor issues: double spaces, missing commas, missing hyphens in
compound adjectives ("well-known", "human-readable", "file-like"),
capitalization errors.
