pyqtgraph-0.9.9 [unreleased]

- Flowcharts and exporters have new pluggin systems
- Version strings:
- __init__.py in git repo now contains latest release version string
(previously, only packaged releases had version strings).

- ComboBox will raise error when adding multiple items of the same name
- ArrowItem.setStyle now updates style options rather than replacing them
- Renamed GraphicsView signals to avoid collision with ViewBox signals that
are wrapped in PlotWidget: sigRangeChanged => sigDeviceRangeChanged and
sigTransformChanged => sigDeviceTransformChanged.
- GLViewWidget.itemsAt() now measures y from top of widget to match mouse
event position.
- Made setPen() methods consistent throughout the package

when plots do not fit inside the widget.

Plotting performance improvements:
- AxisItem shows fewer tick levels in some cases.
