Well good question so far. If you want to remove orca dependency you
need to process the needed info from at-spi in your magnifier application directly.
This would end in writing an screenreader focused on magnification only.
Without at-spi support, your magnifier can't get the needed info about
cursorposition, mouseposition, other application specific details etc.
This means the magnifier must process infos from the a11y interface to
provide useful feedback.
The cursor tracking stuff is missing in the compiz ezoom plugin.
Unfortunately it is the best mag solution available.
