If the script's matrix matches the video's matrix, use that even if
Force BT.601 is on, and if it's TV.601, use that even if Force BT.601 is
off.
This should mostly eliminate the common problems resulting from mixed
values of the Force BT.601 option.
Closes#1649.
For some reason the close event is getting sent multiple times and
them getting processed in the event loop for the confirmation dialog,
resulting in two dialogs.
Split int validating and double validating into two separate classes.
Make double parsing, validating and stringifying locale-aware. This is
far more complicated than it needs to be due to that Aegisub's locale
handling is a total mess.
Use DoubleValidator rather than wxFloatingPointValidator, because the
latter doesn't work with Aegisub's locale mess (on OS X it uses the C
locale for some things, and the locale reported by CoreFoundation for
others).
Closes#1568.
Passing nullptr to ostrstream's constructor is a nonstandard extension
that libc++ doesn't support, and as it turns out preallocating a buffer
doesn't actually meaningfully improve performance anyway.
Reverse iterators behave differently from regular iterators when
swapping (regular iterators continue to point at the same elements,
while reverse iterators do not), so instead use regular iterators with a
negative step for shifting down.
Showing zero is mildly misleading since it's actually default margin
rather than no margin, and this makes it much easier to spot the rows
where there's actually an interesting value.
Even without the animation the reported progress was an average of 1.5
blocks behind the actual progress, and with the animation it was two
blocks behind. Assuming constant-speed audio decoding it should now be
nearly accurate (it still ignores that the last block may be smaller
than the rest).
The wxLogger isn't created until it's needed by the main thread, so any
errors logged on a background thread before the logger was first used on
the main thread were simply being discarded. Fix this by forcing the
creation of the logger very early in the startup process.
