Subject: [PATCH] big patch from Samsung SAIT (Advanced research group) for
 async multi-frame rendering. to turn on:

1.
configure with --enable-async-render
2.
export EVAS_RENDER_MODE=non-blocking

presto. necessitates some api swizzling (thus the expedite. ecore etc. changes)

the kind of results you get on a desktop:
