GES or the video mixer element would need to support overlay composition
meta. So that it can telle text overlay to attach seperate overlay buffer
to the buffer instead of compositing, and these prerendered buffer could
match the output size.

An other approach, without patching GST/GES, would be to create a dedicated
track for the text, with the output size set to the final resolution.
