Create a ImageSurface from a existing cairo_surface_t*.
ImageSurface is a garbage collected class. It will call cairo_surface_destroy
when it gets collected by the GC or when dispose() is called.
Warning:
ptr's reference count is not increased by this function!
Adjust reference count before calling it if necessary
Only use this if you know what your doing!
This function should not be needed for standard cairoD usage.
