[Kjetil Matheussen]

Radium is an open source music editor with a novel interface.
It's inspired by trackers, but has fewer limitations and uses graphics 
to show musical data.

Most important changes 0.65.7 -> 0.67.1:
* Ported GUI to Qt4
* Ported Editor to GTK2.
   (Did this because of bad performance with QT4 2D graphics.
    The editor now runs as an embedded widget in QT4.)
* More colorful default colors
* Various build fixes
* Compiles under MinGW.
   (Tested in wine and Windows7, but it doesn't work very well yet.)
* RELEASE buildtype.
* Fix nodeline selection
* Antialiased lines
* Adjusted tempo colors
* Fix race condition for midi input
* Midi input editing.
* Removed the custom resize window box.
* midi: increased latency from 1.95ms to 5ms. (This should probably be 
configurable)
* Various bug fixes and improvements
