  1. We did a rethink on channels, selections and masks last summer.
  2. Traditionally, a mask is seen as an extra channel for an image, analogous
  3. to the alpha channel. We want to do away with that idea.
  4. A layer can have a number of permanent selections associated with it.
  5. Such a selection can handle a composite method (determining the composition method
  6. for the selected pixels) or a filter (making it an adjustment layer).
  7. Of course, a selection is just an 8-bit per pixel single channel layer that
  8. belongs to a layer, so all filters can work automatically on a selection,
  9. except that we don't have the ui for that yet.
