auto region set: when moused over, set region to mouse location for every bpm toggle
scroll wheel: on scroll, override bpm toggle and change size of region
lock to region: always keep playbar inside of region, do extra checks to see if it escapes region
make scrolling on waveform a little easier to nagivate with keybinds
