+16.11.2010
+ - Fixed mixer maximum and minimum sizes. (Tim)
+ Bit of a tough hack. Is there a better way? Done by sub-classing QScrollArea and catching
+ LayoutRequest events, just before paint events when the window sizes are finally correct.
+ TODO: Still off by a few pixels when mixer first opened, because main window frameSize
+ is not set yet, by the time LayoutRequest is caught.
14.11.2010
- renamed deicsonze2 files and classes with '2' suffixes
- Applied patch by Orcan to convert populateAddSynth(). (Tim)
