I want to support dynamic resizing of my application's 3D view.
As far as I understand, the canvas size is to be stored in PVRShell's prefWidth and prefHeight variables.
In the documentation of `PVRShellSet` it says:
"This function is used to pass preferences to the PVRShell.
If used, it must be called from InitApplication()."
But how can I handle 3D view resizing at runtime? Apparently I cannot set prefWidth/prefHeight when my view frame changes.
