The fallback 'import Image' was added in commit
99621d7a01 for the PIL package. However,
the PIL package is no longer maintained and does not support Python 3.
Development has moved to the Pillow package which always installs to the
PIL namespace.

In Python 3, the default encoding of source files is utf-8. The encoding
cookie is now unnecessary and redundant so remove it. For more details,
see the docs:
https://docs.python.org/3/howto/unicode.html#the-string-type
> The default encoding for Python source code is UTF-8, so you can
> simply include a Unicode character in a string literal ...
Includes a fix for the flake8 header checks to stop expecting an
encoding cookie.
0. do not escape Unicode Greek letters via LaTeX math mark-up: pass them
through un-modified to LaTeX document,
1. if "fontenc" receives extra option LGR, then pdflatex will support
Unicode Greek letters (not in math), and with extra option T2A it
will support (most) Unicode Cyrillic letters.
2. for pdflatex with LGR, this will use "textalpha" LaTeX package and
"substitutefont" package to set up some automatic font substitution
to work around the unavailability of Greek with "times"
package (which is default font package chosen by Sphinx for
pdflatex), same with T2A and "substitutefont" for Cyrillic.
3. for xelatex/lualatex, set up Computer Modern Unicode as default font,
as it supports Cyrillic and Greek scripts,
4. for platex, don't do anything special as the engine already has
its default font supporting Cyrillic and Greek (even in math mode!)

This one is a little unusual. The current theming doc mixes user-focused
documentation with developer-focused documentation. This is confusing
and unnecessary. Resolve the issue by splitting the doc in two. The
user-focused docs are moved to the advanced section of the usage guide,
while the developer docs remain where they are, pending the addition of
a developer guide.
