>                 URL: https://issues.apache.org/jira/browse/FLEX-33989
>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Mobile: ViewNavigator
>    Affects Versions: Apache Flex 4.11.0
>            Reporter: Vincent Spallek

> Steps to reproduce:
> - Create a TabbedViewNavigatorApplication with applicationDPI set to 160 dpi
> - Add a couple of ViewNavigator that have a MultiDPIBitmapSource as icon, and add icons
for another resolution, e.g. 320 dpi
> - Run on a device with that higher resolution
> - Result: higher resolution icons will be loaded and displayed in the proper scale
> - Stop the application and reload it
> - Result: higher resolution icons will be loaded but not scaled properly, so they appear
too large and with low resolution
> Root cause: ViewNavigatorBase discards the MultiDPIBitmapSource information in saveViewData()
and instead only saves the high resolution bitmap. After re-loading in ViewNavigatorBase.loadViewData(),
only the bitmap is restored without the DPI information. Hence, BitmapImage etc. don't have
sufficient information to properly scale the image, see BitmapImage.measure()
