[Gimp-user] New image too large?

[rich404 <forums gimpusers com>]

I should have added 

What gets saved with your .xcf file?

No undo levels. They are only there per-session. Although if you crash Gimp,
there might be a recovery available.

Layers,  Layer Masks, channels, selections, paths, guides, grid settings, meta
data, all saved with the .xcf.

The (extra) compressed version(s) .xcfgz / .xcfbz2 / xcfxz all open straight up
with Gimp just take a bit longer. to save / load.
