- Added support for basic Cursor management. - Added support for NSWindow cancelOperation: callbacks. It's not... perfect, but it works as a discrete hook. - Added support for NSProgressIndicator. - Properly forward Error types from QuickLook generation calls, and future-proof the ThumbnailQuality enum. - Add support for configuring Label line break mode.
