I was thinking of something else for the presets that require algorithms:

 gst_preset_get_algorithms (): returns a list of supported algorithms 
 gst_preset_apply_algorithm (): perform an algorithm on the preset properties.

The naming is probably not very good, what I'm trying to achieve is have at
least 2 predefined algorithms for changing the properties:

 RESTORE_DEFAULTS
 RANDOMIZE

More can be defined, we need get_algorithms() and apply_algorithm to the
vmethods to make this work. It's kindof similar to have presets that start with
an identifier (like *defaults and *randomize) but a bit more explicit.

I still prefer just having the special preset name prefix to mark actions, with
a couple of predefined strings for the actions we support by default.
