Introduce Annotations ItemsSource property

Available in Release Version Q1 2016.

The exception is reproducible when the chart contains series with RenderOptions=Direct2DRenderOptions.

The error message is:

HRESULT: [0x8876086A], Module: [SharpDX.Direct3D9], ApiCode: [D3DERR_NOTAVAILABLE/NotAvailable], Message: Unknown

Currently, if the trackball position is outside the plot area boundaries, the element is not clipped and there is no mechanism that allows clipping it. 

Note: The trackball is the small ellipse that snaps to the data points.

Add mechanism for getting the layout slot of the axis

Possible positions: 
- above or below the X axis 
- left or right of the Y axis

Some of the data points plotted in the chart are not positioned as expected in a scenario with DateTimeContinuousAxis with SmartLabelsMode=SmartStep and PlotMode=OnTicksPadded or BetweenTicks.

PlotArea occasionally stops refreshing in live data scenario with asynchronous updates (multithreading).

Add support for millisecond sampling interval to ChartDataSource.

Implement ChartSeriesLabelDefinition properties as DependencyProperties

Numeric axes should be able to specify their PlotMode as categorical axes do (currently numeric axes use hardcoded OnTicks plot mode).

Users should be able to create custom financial indicators.

Extend ChartSelectionBehavior to support continuous range selection through drag&drop.

When this mode is on - all of the points for which information in the track ball is shown should be on the left hand side of the mouse.

Set the DataContext of a Candlestick to be the DataPoint to allow binding to properties of the business object.

When this mode is on, information should be displayed for all data points in a given category (as opposed to displaying the closest points taken from different categories).

When the CartesianPlotBand annotation is bound to the vertical axis its 'From' value doesn't align with the axis.
This changes when resizing.

Add grid line style selector

Implement Waterfall series type (http://en.wikipedia.org/wiki/Waterfall_chart).

Currently plot band and marked zone annotations are not snapped to the ticks when the PlotMode of a CategoricalAxis is BetweenTicks. Instead the annotation starts from the middle of the slot, and from the middle of the bar (when using BarSeries). 

Introduce a way to snap plot band annotations and marked zone annotations to the ticks instead of the middle of the slot of the categorical axis.
