Corrscope

This build is stable, but does not have all features/changes planned for 0.3.0.

Incomplete changelog:

- Add stereo rendering GUI (204)
- Add color pickers
- Line width is in pixels. (Previously in points. Multiply by 4/3 to convert to pixels.)

0.2.1 will be released in the future, with improved GUI (eg. color pickers) and a user manual.

Breaking Changes
- Switch Windows builds to Python 3.7 x64 (possible speed boost, larger binaries, similar-sized 7z downloads)
- Remove obsolete config options (breaks compatibility with pre-0.1.0 configs)
- Move ffmpeg PATH into appdata (rather than application folder)

New Features
- Save most recent config/WAV folder, as well as video render folder (separately or together).
- Add GUI tab for preview-only performance tweaks (disabled when recording to mp4)
- Add gridlines and H/V midlines
- Add support for stereo-subtraction flattening

Changelog
- Large speed boost in line-drawing code (save background once, only redraw lines per frame)
- Skip unrecognized fields when loading YAML files
- Fix random exceptions when closing ffplay on Windows
- Tell user to install ffplay (not just ffmpeg) if missing
- GUI: renamed "video size" to resolution, "play" to "preview"
- Windows builds: Add app version number to folder name

Bugfixes
- Eliminate long delay when loading stereo WAV files
- Makes mono WAV files faster. Makes stereo WAV files slightly slower on Linux, possibly more on Windows.
- Eliminate long delay when starting app on Windows
- First run will take 10 seconds (to generate font cache), later runs should take 3 or less.
- Accept invalid .wav with header metadata larger than filesize
- Fix freeze when rendering via GUI
- Strip quotes when user pastes "master audio" with quotes. Fix crashes when adding channels with invalid "master audio".

Changelog
- Tell user to install ffmpeg if missing
- Improve error messages (add stack traces)
- Add app version to title bar
- Mark GUI as edited when browsing for file, or adding/reordering channels

Initial release.

- PyQt GUI

Known bugs:

- GUI loads slowly on Windows (up to 8 seconds)
- Stereo files load slowly (will be fixed soon)

Featured in my Youtube video (https://youtu.be/DcwqdeJ7DSk ). This version has a more "responsive" trigger that jumps around less than before. Unfortunately the bass seems to lag behind.
