I forgot to add one more item to my list of potential/desired
enhancements of GeglBuffer and that is to make the extent (width and
heights) of the buffer be updated on demand when tiles are changed,
allowing automatically growing buffers that are "auto-clipped" to the
bounding box of content that differs from the configured background
color.
