the necessary region of the buffer, instead of performing the
validation implicitly by iterating over the region. This is both
simpler, and, more importantly, allows us to render the entire

considerably more efficient, especially with high thread counts.
This essentially extends the dynamic sizing of rendered projection
chunks to layer groups, which are rendered through
gimp:buffer-source-validate, rather than just the main image
projection.
