content
Same as contentBounds.
Parameters
clip
When true, the bounds will be clipped to the visible area within the viewport. When false, the bounds include the entirety of the content, even areas outside the viewport.
The visible bounds of the content after user zoom and pan. This is calculated by applying contentScale and contentAlignment to the value passed to ZoomableState.setContentLocation.
This value will be SpatialRect.Unspecified if the content hasn't been measured yet, and it will never exceed the viewport bounds.
