[Gegl-developer] A GEGL Tile Interface

[Martin Nordholts]

Hello!

I've been thinking about how an Undo/Redo implementation in an image 
manipulating program that uses GEGL would look. From what I can tell, 
most IMPs uses tiles for Undo/Redo implementations; after an operation, 
they store the changed tiles. On an undo, the changed tiles are reverted 
back.

However, the current gegl.h seems to offer no interface for tile access. 
Has there been any discussion about this, i.e. is a tile interface 
supposed to be available in GEGL?

Sincerely,
Martin
