+21.09.2011:
+ - Drawing speed boosts in part canvas. TODO Fix slight dashed border shifting. Do 'hidden' polygons (Tim)
+ - Working on meter speed. WIP. Can enable by commenting out #define _USE_NEW_METERS in meter.cpp (Tim)
+ Combined with part canvas fixes, meter work so far makes MusE2 near-Muse1 speed when playing big songs
+ with many active mixer strip meters.
20.09.2011:
- Revert the change in coloring of the selected track in tlist. Making full transpaency optional
requires more substantial changes. (Orcan)
