FWIW this code is important for very old versions of lyx, older than 1.1.5 (released 19 years ago - 2000/06/06).
Funny fact of the day, byte strings do not behave as regular strings in python3 when taking and index.
To get a sub-string we need to pass a range, a integer index will not work as it happens in a regular string:
$ ipython3
...
In [30]: line
Out[30]: b'#This file was created by <mike> Tue Jan 25 10:36:51 2000'
In [31]: line[0]
Out[31]: 35
In [32]: line[0:1]
Out[32]: b'#'
The range notations works for both byte and regular strings in python 3, and it also works in python 2.
Thus the change is simple and effective. In any case I should confess that I was quite surprised by this. :-)
In python it is possible to compare tuples with a lexicographic order.
Take advantage of that since there is no need to resort to the C-trick of converting a version in hex format.
We need to set a dummy version in case we are using ImageMagick to ensure that version is always an integer 3-tuple.
It worked in python2 but not the way the authors imagined. Because hex always returns a string.
From python2:
>>> 1 > "2"
False
>>> "2" > 1
True
>>> "1" > 2
True
The rational is that an integer is always smaller than a string.
In python 3 this because it does not make sense to compare objects of different types.

Tested cases are now handled fine.
(There are still many cases where the language support emulation
is too complex for lyx2lyx and manual fixes are required after
lyx2lyx conversion.)
Correct or activate some already present shortcuts, and add new ones
for easily obtaining the most common fixed size delimiters.
Pressing '*' after a delimiter will cycle through all sizes.
This is related to the bug #11457 saga and it was my fault.
The debug files should be written only be on if the argument --debug is passed and not --verbose as it was done by mistake.
This effectively allow paragraph breaks in insets only for cosmetic
reasons (e.g., to align contents on different lines).
This is the last change necessary for an enhanced covington gloss support
(which uses the new covington gloss ui)
In python 3 the colors need to be strings and not bytes:
This was the equivalent of
>> print("%s" % b"1")
"b'1'"
since the colors were bytes the call to dvipng was something like
dvipng -Ttight -depth -height -D 115 -fg "b'rgb 0.937255 0.941176 0.945098'" -bg "b'rgb 0.137255 0.149020 0.160784'" "lyxpreviewxBJEqm.dvi"
Note the "b'rgb after both -fg and -bg that wrecked havoc and thus dvipng failed. That was the difference between python2 and python3 calls.
The "Rows & Columns" optional submenu is more easily accessible in
the math context menu rather having to navigate to the "Edit" menu.
All possible accelerators are already taken, so use the space bar.
Same for BackTab. The outline-in was originally (31398779)
introduced to the command-sequence at the end. Probably it was
placed at the end to be conservative (i.e., so that it would only
change behavior where there was a no-op before).
This fixes#11576.
