crossfade hack and slash. removed overlap checks, overlap mode, default length, fade_is_xfade, fade_is_short, and other leftovers from previous crossfade models. Draw crossfade drags in realtime so fade_line is no longer needed. remove code for hiding crossfades during a drag. moved crossfade rect to top layer so crossfade lines dont grab mouse focus. drag-trim-with-fixed-fade-anchor is partially implemented and needs discussion
