AbsoluteMinimum AbsoluteMaximum AreaSeries different behavior on Android and iOS Xamarin Forms #57

Steps to reproduce

Sample solution: https://drive.google.com/file/d/0B8YvbPIswXQ4aklmYU0xaXR1Yjg/view?usp=sharing

The gist is to plot an AreaSeries that has endpoints defined outside of the X-axis's minimum and maximum values. If AbsoluteMinimum and AbsoluteMaximum are set on the X-axis, then the series will be filled on iOS, but not on Android.

1. Create a plot with a TimeSpanAxis and a LinearAxis. Set Minimum, Maximum, AbsoluteMinimum, and AbsoluteMaximum value on the TimeSpanAxis and Minimum and Maximum on the LinearAxis.
2. Add an AreaSeries to the plot. Add two DataPoints to the AreaSeries, one with X less than the TimeSpanAxis's Minimum and one with X greater than the TimeSpanAxis's Maximum. Set Y values on the DataPoints. Set a fill color.
3. Render the plot in a PlotView.

Platform: Xamarin.Forms Android and iOS
.NET version: 4.5
