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.
Use boost::filesystem::path for all paths, and std::string for all other
strings, converting to/from wxString as close to the actual uses of wx
as possible.
Where possible, replace the uses of non-UI wxWidgets functionality with
the additions to the standard library in C++11, or the equivalents in
boost.
Move the path token management logic to libaegisub (and rewrite it in
the process).
Add a basic thread pool based on asio and std::thread to libaegisub.
This touches nearly every file in the project and a nontrivial amount of
code had to be rewritten entirely, so there's probably a lot of broken
stuff.
The video source's copy of the subtitle file was being discarded once it
was fully loaded (as it was previously never needed again), so amending
it only worked if the user had made a non-amend commit after the last
seek.
When the set of changed lines is populated, only copy those lines rather
than the entire file. On large files, this makes amend commits roughly
twice as fast when video is open.
Mostly just bugs in unreachable code and stylistic things, but there's a
few incorrect reachable things that were working by coincidence and
gratuitous dynamic_casts.
Don't display error messages and try other providers when the user
cancels loading a file.
Remove files from the MRU lists if they can't be found.
Closes#717.
Originally committed to SVN as r4717.
Makes the click event handler for the grid no longer slow when video
autoscroll is enabled, making it harder to accidently select multiple
lines.
Makes seeking speed no longer limited by decoding/rendering speed;
seeking faster than video can be decoded simply results in dropped
frames.
Makes editing the file while a slow-rendering frame is visible far more
responsive.
Originally committed to SVN as r4702.
