annotate layer/TextLayer.h @ 35:10ba9276a315

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
* Add TextModel and TextLayer types * Make View refresh work better when editing a model (previously edits might not be refreshed if their visible changed area extended beyond the strict frame range that was being modified in the model) * Add phase-adjusted instantaneous frequency display to spectrogram layer (still a work in progress) * Pull maths aliases out into a separate header in dsp/maths so MathUtilities can be included without introducing them
