* docs/undo.txt
Changed sanity checks in undo_pop/free_layer_mask() to LAYER_MASK_ADD_UNDO
and LAYER_MASK_REMOVE_UNDO to be consistent with undo_push_layer_mask()
These now nvoke proper cleanup and release of GimpLayerMasks.
* docs/undo.txt: New file, an overview of undo logic written by
Austin Donnelly
* app/undo.c
* app/undo_types.h
* app/gimpimage.c : Introduced a new UndoType, UNDO_NULL, which maps
to zero, introducing that value into the enumerated types. Use the
type to signal type unknown/error/untyped conditions.
