The patched meson.build for dav1d just changes the include_directories
from 'include/dav1d' to 'include' and, while we're at it, removes the
pkg_config stuff to avoid a deprecation warning.
AV1 decoding is pretty broken in upstream ffms2, so point the wrap to a
fork that has some hack patches for it. BestSource works fine out of the
box, though.
This is nothing more than duct tape, do not pull.
In the long run boost::filesystem should just be replaced with
std::filesystem (as done in tgoyne/Aegisub:cmake), but this would
complicate the history and cause merge conflicts for a bunch of pulls.
Hence this horrible temporary solution.
When Avisynth is not installed or not functional, this would otherwise
cause a crash when trying to initialize Avisynth more than once, since
after the first time the refcount would have been incrased anyway.
Also, allow negative fsp.
This doesn't change the behaviour of the SpinCtrl increment/decrement
buttons, just the precision that can manually be set. Small values of
fsp can be useful as a hack to disable all ligatures. Precise values of
fscx/fscy can be useful to compensate for anamorphic resolutions. The
other fields were made more precise for consistency.
This fixes a crash on Windows when double-clicking the draggable
separator between the column headers "Command" and "Description" in the
hotkey configuration dialog.
This makes the internal juggling of fold data even more complicated, but
it has a number of advantages:
- Folds will preserved even when opening the file with Aegisub builds
that don't know about folding.
- Folds will be preserved by automation scripts that re-insert every
line.
- Folds do not break when adding or deleting lines in a text editor or
some other editor, as long as the lines involving folds aren't
touched.
- In particular, merging changes using tools like git will not break
folds.
- Copy/pasting folds also keeps the folds to some extent. This is
impossible to solve in full generality, but simple cases like
cut/pasting a folded section somewhere else work, as long as the file
isn't saved in between.
- This will give automation scripts full access to folding without
needing to set up any additional API functions.
