Similar to the recent adoption of Black. isort is a Python utility to
sort imports alphabetically and automatically separate into sections. By
using isort, contributors can quickly and automatically conform to the
projects style without thinking. Just let the tool do it.
Uses the configuration recommended by the Black to avoid conflicts of
style.
Rewrite TestImageQt.test_deprecated to no rely on import order.
On truncated jpeg, decoder can suspend waiting for additional bytes in
buffer. For some input files, decoder suspends on jpeg_start_decompress
stage. If at this point file reader reaches EOF, py code never gets back
to jpeg decoder and we end up with no bytes to result image. This leaves
us with some amount of potentially useful bytes undecoded and thrown
away.
Libjpeg docs suggest that in such situation, more appropriate would be
to add EOI marker to the end of buffer, which will allows decoder
to finish. https://github.com/libjpeg-turbo/libjpeg-turbo/blob/0dd9a2c1fd6c/libjpeg.txt#L1803-L1809
Docs also mention that adding EOI markers is what non-suspending code
does anyway.
