annotate base/Resampler.h @ 297:c022976d18e8

* Merge from sv-match-alignment branch (excluding alignment-specific document). - add aggregate wave model (not yet complete enough to be added as a true model in a layer, but there's potential) - add play solo mode - add alignment model -- unused in plain SV - fix two plugin leaks - add m3u playlist support (opens all files at once, potentially hazardous) - fix retrieval of pre-encoded URLs - add ability to resample audio files on import, so as to match rates with other files previously loaded; add preference for same - add preliminary support in transform code for range and rate of transform input - reorganise preferences dialog, move dark-background option to preferences, add option for temporary directory location
