- disabled opengl (performance issues in Qt 4.7)
- numerous caching changes (disabled deviceCoordinateCache due to performance issues)
- speed up loading large images in ImageView
- bugfixes from Ingo Breßler
- Transform rotation bugfix
- Added debug module
- Major performance enhancements for scatterplot, fixed point clicking issues
** API change for scatterplot click signals
- Drawing on ImageItem is working well now
- PlotItem downsampling no longer uses scipy.signal.resample (this was creating artifacts)
- Fixed ViewBox behavior when aspect-locked
