When the ShapeTool is active and you execute another tool (lets say DrawTool) the UI becomes partially unresponsive. This includes the tools section and the tool settings panel.

The issue is reproducible in a NoXaml scenario (using implicit styles) and only if the Telerik.Windowls.Controls.ImageEditor.xaml ResourceDictionary is merged in the resources of the view where the control is defined (example: MainWindow.Resources).

To work this around define the ResourceDictionary in App.xaml.

When RadBitmap objects which sources are big images (e.g. 2000x1500) are rotate, image quality loss is observed. Internally, RadBitmap.Rotate method is used.

When a RadBitmap is rotated to degrees for which sine and cosine are not integers (every angle which is not 90, 180, 270 or 360) applies wrongly calculated transformations and the bitmap' size is no longer correct.

For example, rotating a bitmap to -30 and then to 30 degrees changes its size.
