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.
Originally committed to SVN as r5613.
* Wrapping all headers that are in agi_pre.h with AGI_PRE.
* Sorting alphabetically.
* Same operation as r3515.
Note: This is broken when precompiled headers are not in use, I'll fix that after this commit so the two changes don't get jumbled up.
Originally committed to SVN as r3525.
* Update agi_pre.h to include some missing headers, also move required windowsheaders to the top of the list
* Use <> versus "" for the wx header in avisynth_wrap.cpp
* Remove xx/wx.h from agi_pre.h as it's included by wxprec.h.
