- Fixed some floating-point precision issues. (Added a workaround for QTransform.inverted() bug)
- No longer putting asUnicode inside __builtin__ since this causes problems in some rare circumstances
(pyshell, lazy import recipe)
- Minor docstring updates
Moved GraphicsScene to its own directory, added exportDialog
Removed old export options from PlotItem / ViewBox (will re-enable once they are working again)
