Gimp/app/interface.c
Lauri Alanko ef3e162eae start collecting some core stuff to libgimpim.a 
Started separating crud out of drawables.

	Isolated the id system of images entirely within pdb. Even the
	window titles and menus use pointers instead of ids. Should at
	least remind people that this is a developers' version. :)
