The relative order of the on-file-load logic matters, so signals don't
work very well for it. Doing it all explicitly in Project fixes a bunch
of inconsistent issues related to restoring saved state.
Closes#1759.
A lot of the wxDialog subclasses don't actually override any virtual
functions, so there's no particular need for them to be subclasses at
all, and wxDialog's vtable is so huge that they actually contribute
measureable to the size of the executable.
It's modestly faster, significantly more type-safe, and doesn't assert
when there's too few arguments, which causes problems for plural forms.
Closes#1733.
It drags in a ton of crap, is kinda slow at runtime due to using
std::deque, and doesn't actually make the code much simpler than just
using a manual ring buffer.
Use std::chrono since it's a nicer API. Use a separate lock for playback
position so that the GUI thread isn't blocked for hundreds of ms while
snd_pcm_drain is waiting, and update the playback position after
decoding audio rather than before to avoid it being significantly wrong
when not using a cache.
If video was previously open and the user chooses to resample the script
for the new video, VideoController would try to update the subs for the
now-deleted old provider.
Fixes errors when trying to automatically open audio from dummy video
and improves UX a little by disabling the Open Audio From Video menu
item when there are no audio tracks.
Most of the dialogs in Aegisub have a public interface consisting of a
single function, so there's really no need to expose the actual dialog
classes to the rest of the program. Add dialogs.h with the declarations
of all of those functions (most of which are just ShowFooDialog()), and
kill a million other headers.
