Improve text font support.
Improve naming to differentiate between text fonts and music fonts (for engraving).
Remove DEFAULT_ prefix.
Use Font.SERIF and Font.SANS_SERIF instead of 'Times' and 'Arial'.
Rename getFontStack().

…ing VexFlow tests.

This fixes the test case: ChordSymbol › Chord Symbol Font Size Tests › Canvas + Bravura

Publish npm package vexflow-fonts (stored in tools/woff/).
This allows the *.woff, *.woff2, and *.otf to be hosted on unpkg/jsdelivr.
flow.html loads the web fonts directly from unpkg.

Command line QUnit test now uses flow-headless-browser.html instead (it's
much simpler).

Improve how we handle default static TEXT_FONT.
Factory.Annotation(params) now takes a FontInfo object.
Note: Factory.Annotation() has a different default font than new Annotation().
Rename this.textFont to this.textFormatter.

This allows us to use fragment identifiers to scroll directly
to a test case (by using the name of the PNG file generated by
our visual regression tests).

Explore loading custom fonts in node JS.

Temporarily get back to zero visual diffs for the purposes of code
review by unfixing some bugs:
- restore inconsistent font families.
- restore the bug in ChordSymbol + PetalumaScript.

Methods remaining in TextFont deal with formatting / metrics.
TextFont will be renamed to TextFormatter.

Rename TextFontTests to FontTests.
Remove unused code.

Attempt to read/write OTF files. Cannot currently convert to WOFF.
Continue to rely on FontSquirrel for now.
Use the FontSquirrel version of PetalumaScript for better kerning.
Add information on how to convert the OTF to WOFF via FontSquirrel.

Move OTF files. Bump vexflow-fonts. Clean up font scripts.

Update the legacy glyphs.html and transform.html.

Use a precomputed string as a key for the glyph cache.
Move new glyph inspector and legacy font tools to tools/fonts/.
Update CHANGELOG.

Fix visual diff in textbracket_tests.ts.
More clean up.

- Support all fonts.
- Support both OTF and extracted outlines.
Add more documentation.
Other small fixes.

Improve OTF glyph inspector (Gonville font).
Fix demos.
Discovered a potential API stumbling block by writing tests.

Add .font setter/getter to Element and rename internal instance member to `textFont`.
Add test code for setFont() in tests/font_tests.ts.
Other smaller fixes.

JSON output.

Fix Gruntfile and tsconfig to emit .d.ts and support ESM.
Improve flow.html.

Review tests/* for API differences. Mark changed lines with
"RONYEH" and revert those lines to current master where possible.
This is only for simplifying the code review. Afterward, I will
add a single commit re-introducing all the commented-out lines, which
will result in small visual diffs in the output.

Revert setFont(...) and .font='...' calls to current master, to
demonstrate the 4.0 API is (mostly) backwards compatible.
For extra robustness (and backwards compatibility), we support empty
strings for weight & style. '' is equivalent to 'normal'.

declarations.
Fix eslint warnings.

to support older TS compilers that complain about object spread with
undefined.

Fix comments.

Includes relative path imports for test files from:
0xfe#1209

Update demos.
Fix capitalization.
Fix README. eslint autofix markdown and JS.

Fix an integration issue where common.d.ts isn't exported but it
is referenced by TS files.
Solution: remove common.d.ts and move types to where they are actually used.

Fix issues caused by renaming output files.
