Alexei Podtelezhnikov b070264521 * src/smooth/ftgrays.c (gray_hline): Simplify even-odd computations.

Ben Wagner 82fd32d674 * src/cid/cidload.c (cid_hex_to_binary): Improve return value.
Add argument to return the actual number of bytes that were decoded.
The actual number of bytes decoded can be quite variable depending
on the number of ignored 'whitespace' bytes or early termination
with `>`.
(cid_face_open): Updated to use this calculated value.  This avoids
trusting `parser->binary_length` is always be correct and reading
uninitialized bits if fewer are actually decoded.

Alexei Podtelezhnikov 66630d882c [sfnt] Streamline POST format 2.0 handing.
