Some way of being able to query value ranges of the interface properties in the
GstPhotography would be very good. Right now it can be done for example by
using the V4L2 interface (if using v4l2src) directly, but it is very ugly and
makes the implementation depend on things below the gstreamer layer.

Useful properties from the properties would also be the following:
- step size
- default value

Also the notifications of value changes are useful. I do not know enough about
the Gstreamer internals to say which would be a good way to implement these,
though.
