commit 3bd674ee392d650ef307bb8d4c046282a8dad918
Author: Jehan <jehan girinstud io>
Date: Mon Jul 25 01:08:11 2016 +0200
plug-ins: cache panels directly as GEGL buffers.
Do not use an internal GIMP image anymore and do all the dirty work
directly in GEGL graphs.
Also pre-compute updated frames as soon as possible (instead of the last
second when it is needed at playback) as a cache system.
