Also speedup getting url for hyperlink id by using a second hash map for
it. Change behavior when there are too many hyperlinks to discard new
hyperlinks instead of remapping old hyperlink id and making some old
hyperlink wrong.
Follow PEP 0394 and use /usr/bin/env python so that the python in the
users venv is respected. Not that the kitty python files are meant to be
executed standalone anyway, but, whatever.
Fixes#6810
This allows us to have newline not affect the wrap status of a line.
Now a lines wrapping status is changed only when the last cell
in the line is changed. This actually matches the behavior of many other
terminal emulators so is probably a good thing from a ecosystem
compatibility perspective.
The fish shell expects this weird behavior of newline not changing
wrapping status, for unknown reasons, which is the actual motivation for
doing all this work.
Fixes#5766
At some point, unicode regional indicators became combining chars in the
unicode standard, which broke the handling of them in draw_codepoint().
The fix has the added advantage of improving performance in the common
case by only checking for combining chars. The flag check happens only
if the first check matches.
Fixes#4407
Also roundtrip all characters in the Cf category.
Characters with the DI (Default Ignorable) property are now
preserved but not rendered and treated as zero-width
as per the unicode standard.

A better solution from an ecosystem perspective is to just work with the
original protocol. I have modified kitty's escape parser to special case
OSC 52 handling without changing its max escape code size.
Basically, it works by splitting up OSC 52 escape codes longer than the
max size into a series of partial OSC 52 escape codes. These get
dispatched to the UI layer where it accumulates them upto the 8MB limit
and then sends to clipboard when the partial sequence ends.
