desruisseaux pushed a change to branch geoapi-4.0
in repository https://gitbox.apache.org/repos/asf/sis.git


    from 297e7a67fe Refactor `WritableRenderedImage`support in 
`BandedSampleConverter` for sharing more code with other writable images. 
Refactor `BandAggregateImage` by moving its inner helper class outside, and add 
`WritableRenderedImage`support. `BandAggregateImage` is no longer an "all or 
nothing" implementation: can have a mix of shared and copied arrays.
     new 65c2a49846 Make `getTileWidth()` and `getTileHeight()` methods final 
in `ComputedImage`. Add design notes in Javadoc for explaining some rational.
     new d3164ba70d Add a `MultiSourceImage` package-private abstract class and 
add support for prefetch operation.
     new 6c85b283c4 Result of "band select" operation should be writable if the 
image is writable.

The 3 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails.  The revisions
listed as "add" were already present in the repository and have only
