In theory, you can use the producer named "consumer." It encapsulates a
consumer running with a different profile than the outer graph/project's
profile. Then, the auto-attached normalizing filters take care of things
like scaling and padding to adapt the nested consumer's output to the outer
profile. However, this is not working correctly with webvfx based on my
test today to provide you with an example.
If you are providing and controlling the HTML, then I suggest you take care
of what you need to do in there. If not, then there ought to be an API for
Qt WebKit to adjust the zoom factor just as a browser GUI does. You could
look into that, hook it up to a MLT property, and submit a patch for this.
