The secondary_editor is a wxTextCtrl, whose height is calculated from 2 rows of text. Using this height gives better consistency on screens with different DPIs, instead of using hard coded value like 50px
Since FileNotFound exceptions don't abort the provider search, opening
an invalid path would show errors such as "vapoursynth not found" when
VapourSynth wasn't installed, even if VapourSynth wasn't selected as the
default video provider.
This default script will be executed to load any file whose file name
extension is not .py or .vpy .
The gui code for setting the default script is still a bit wonky as it
doesn't fit the rest of the preferences pages nicely, but it works for
now.
Since FileNotFound exceptions don't abort the provider search, opening
an invalid path would show errors such as "avisynth not found" when
Avisynth wasn't installed, even if Avisynth wasn't selected as the video
provider.
When cancelling an automation macro from the progress dialog, the dialog
throws a UserCancelException. If the macro still runs to the end
afterwards (instead of calling aegisub.cancel or causing an exception),
the two return values are left on the stack. This causes assertion errors
due to check_stack when those are enabled.
Some of these got lost in the process before.
For now, default to 709 if the colorspace is unkown. More detailed
colorspace guessing can be added in the future.
These alignment flags would cause an assertion error
"Horizontal alignment flags are ignored in horizontal sizers"
when opening the dialog (mainly when importing styles from another
script).
As the assertion error says, the flags are ignored anyway, so they're
safe to remove.
After the audio provider rework, adjust the audio players to not
use the int16 mono downmixed audio unless necessary. Furthermore,
the pulseaudio-based player now controls the volume directly through
pulseaudio instead of by modifying the buffer. This also reduces latency
when changing the volume.
The entire set of GetAudio functions is quite messy now. After wangqr's
audio rework, it was split into GetAudio and GetInt16MonoAudio
functions, but now volume scaling is also necessary. Really, this should
go back to a type constructor based system with audio players being
allowed to choose what properties out of mono / 16 bytes / int samples /
volume they need.
