This is fixed. The problem was that 's' is an alias to 'width' and
'height,' which are also profile settings, but the profile was not
being updated. The same problem occurred with 'aspect,' which is now
fixed too. Also, I added support for 'r' that corresponds to frame
rate; however, this is not yet suitable for use within kdenlive due to
the #1 item on my todo list:

http://www.mltframework.org/twiki/bin/view/MLT/ToDo

This was already mentioned, but it is worth repeating. Currently, all
operations and westley authoring is expressed in frame units and is
stored that way internally, which means it does not scale with changes
in frame rate. All durations and timing are currently expressed in the
context of some predetermined frame rate (the project settings in
kdenlive). Still, something like -r is handy for simple transcoding.
