Rather than everything having to separately commit changes to the ass
and then tell the subs grid to notify various parts of Aegisub about the
changes, committing the AssFile now triggers an event which objects
listen for.
AssFile::Commit now also has an argument to indicate what sorts of
changes were made to the file. For now these types are very broad.

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.

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.
Rather than just have a single Refresh method that gets called whenever
something happens that could possibly be of interest to the visual
tools, add seperate methods for signaling frame number changes and
changes to the file, and use the new SelectionController stuff for other
things that used to merit a Refresh. This eliminates a large amount of
redundant reparsing of lines which happened on paint, as well as a large
number of redundant repaints.
Frame data is now only uploaded to the video card when the frame number changes
rather than when anything at all changes, slightly improving performance when
using mesa's software opengl implementation.
Vector clip and drag tools now do a slightly better job of not
discarding the user's selection for no apparent reason, and strange
selection behavior from clicking on visual features should now be
entirely fixed.
Everything but the constructor and toolbar event handler in the visual
tool implementations are now private.
Originally committed to SVN as r4631.
Selections in drag mode now follow the following rules:
* If a line is selected in the grid, at least one visual feature
corresponding to the line is selected.
* If a line has any features selected, that line is selected in the
grid.
In addition, all control points now start out selected in the vector
clip tool, and all tools should no longer discard the current selection
at unpredictable or unintended times.
Updates #513.
Originally committed to SVN as r4363.
Previously the visual typesetting tools and the overlay mask used
several coordinate frames, converting between them in many places in
inconsistent ways. This elimiates all uses of coordinate frames other
than screen and script, and makes the conversion done in one place, and
only when parsing or serializing ASS.
This fixes:
- A few minor rounding errors
- Horrible brokeness when only part of the video frame is being
displayed, due to higher levels of zoom than fit onscreen or panning
the video
- Distortion of the visual typesetting tools when the combination of
overridden aspect ratio, script resolution, and video resolution did
not result in square pixels.
- Resolution-dependence of the visual typesetting tools, which resulted
in some tools becoming hard to use at zooms outside the range of
100-200%.
- Some draggable controls used the mouse's script coordinates,
resulting in noticable jerky movement at high zoom levels or when
using strange script resolutions.
Closes#966.
