Convert all coordinates within the visual tools to Vector2D, which has
been significantly extended. Eliminates a lot of issues with accumulated
rounding errors and simplifies a lot of code.
Modernize the visual tools' interactions with the rest of Aegisub by
connecting to signals directly rather than routing everything through
the video display and converting the main visual tool mode toolbar to
the command system.
Extract all references to OpenGL from the visual tools and move them to
OpenGLWrapper as a first step towards making it possible to implement an
alternative video renderer. In the process, eliminate all uses of OpenGL
immediate mode.
Fix a bunch of minor issues and general instability.
Originally committed to SVN as r5823.
Move most karaoke parsing/serializing/editing code to AssKaraoke rather
than being scattered all over the place, and add much better support for
non-karaoke override tags and comments.
Add a karaoke timing controller.
Redesign the karaoke syllable split/join interface to have a single mode
from which both splitting and joining can be done rather than separate
split and join modes.
Only show the karaoke split/join bar when karaoke mode is enabled.
Closes#886, #987, #1190.

Remove the Matroska keyframe/timecode loading code, as opening MKVs via
Avisynth is dumb and didn't work very well anyway.
Fix framerate reporting by actually bothering to read the video
information before trying to use it.
Kill the VFW wrapper and just put the code in the avisynth video source.
If reading the keyframes from an avi file fails just warn the user
rather than refuse to load the video.
Originally committed to SVN as r5558.
Remove hardcoded assumptions about where in the menu items are and
instead bind menu items directly to commands so that customizing the
menu actually works.
Add support for user menu files that override the default one.
Add better support for multiple menus so that all of the menus can
potentially be created by the dynamic menu system rather than just the
main menu bar.
Add support for commands whose names change based on the current project
state so that undo and redo can work properly.
Simplify the menu json format and make commands responsible for
controlling what type of menu item is created rather than allowing
nonsensical configurations.
The Automation menu is currently not implemented.
Originally committed to SVN as r5554.
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.
This happens to fix most of the undo issues, as it's now much harder to
have uncommitted changes to the file.
Closes#355 and #586.
Originally committed to SVN as r4699.
Kill vfr.h and vfr.cpp and use the libaegisub versions of them instead.
Rather than the globals VFR_Input and VFR_Output, everything related to
frame rate is now part of the video context. Most things which used to
use VFR_Output now call VideoContext::TimeAtFrame etc.; video providers,
rather than modifying VFR_Input directly, now have getters for their
frame rates which VideoContext calls. Read-only public access to
VFR_Input and VFR_Output are still provided (hopefully temporarily) for
a few things which were awkward to do through VideoContext.
The Avisynth provider now might correctly handle VFR MKVs which can be
opened with DirectShowSource but not DSS2.
Rework keyframe handling as well, so that it continues to match the vfr
handling in design and implementation.
Originally committed to SVN as r4662.
