Take a
Project, a size for the image tiles, and a target directory,
and create a new copy of the current project in that folder but with the underlying
images converted to tiles with a translation-only transform (saved as zipped TIFFs,
with extension ".tif.zip"). |

tileSequence(Layer srcLayer,
int tileWidth,

boolean onlyVisibleImages)
Return a lazy sequence of Rectangle instances, each specifying a tile that contains at least
parts of one Patch.

Project, a size for the image tiles, and a target directory,
and create a new copy of the current project in that folder but with the underlying
images converted to tiles with a translation-only transform (saved as zipped TIFFs,
with extension ".tif.zip").
The new, returned Project represents the given project but with much
simpler transformations (just translation) for the images and a defined size for
the latter, which helps a lot regarding storage space of the XML (and parsing and
saving time) and performance when browsing layers (keep in mind that, for a 32k x 32k image,
at 100% zoom one would have to load a 32k x 32k image and render just a tiny bit
of it). The copied Project preserves the ID of the Layers of the original
Project, as well as the dimensions; this means the copy is a sibling of
the original, and it is possible to send segmentations from one to the other "as is"
(directly, without having to transform along with the images which would not be possible).
