Implement "find glyphs that use glyph" for designspace backend #1214

justvanrossum · 2024-03-17T08:46:06Z

add fontra.backends.utils module for small functions that have no good other place
add fontra.backends.glyphdependencies helper module to keep track of glyph dependencies
rename getGlyphsUsedBy() to findGlyphsThatUseGlyph() (less ambiguous)
add optional startOptionalBackgroundTasks() method to give backends a chance do some indexing without blocking regular loading
