Type: System.Windows.UIElement
The element to be rendered within the bitmap.

After calling this method, you must call Invalidate in order to render the bitmap.

This method does support UIElement objects that are not part of the visual tree. You are required to call Measure and Arrange for UIElement objects that are not in the visual tree, before calling Render.

If the element is larger than the size of the bitmap, or if the element has any points in the negative regions of its own space, it is clipped as appropriate.
