Thanks, good to know, again for small steps, I suggest to expose it as a range
in GST to prevent the caps size becoming too big. For sources, we can always
get it to round up, and crop. Loosing a border of 1 or 2 pixels won't make much
difference (cameras are already cropping a bit), and I expect that standard
resolution are supported in most cases.

Right now, a lot of HW have hidden steps, so we need a way to handle that
anyway. On blocker I have, is that v4l2 device do a round neared, rather then
useful round up.
