Some elements have such a property, others not. In theory you could set
the passthrough setting of GstBaseTransform from the outside, but in
practice this will confuse elements and cause many problems.

A passthrough property on videoscale also does not seem to make any
sense (or on any converter). Those elements are already passthrough if
nothing has to be done. And if something has to be done, going into
passthrough instead would cause a negotiation error.
