1) New region expansion code to propagate wave from a boundary
of a region inside of it.
2) get_extents() extended with a template attribute to work with
zero area data sets.
3) ClipperZUtils.hpp for handling Clipper operation with Z coordinate
(for source contour identification)
worker threads: QOS_CLASS_USER_INTERACTIVE.
The one level lower QOS_CLASS_USER_INITIATED makes our tester Filip
unhappy, because when slicing tree supports Filip switches to a browser
on another display wating for the slicer to finish, while OSX moves
the slicing threads to high efficiency low coal burning cores.
PrusaLink: Use PUT or POST based on information read during test connection (upload-by-put). If put - do additional GET for storage_list and let user to choose where to upload or show name if only 1 is possible. Allow PrusaLink for MK2.5 and MK2.5S.
PrusaConnect: New host type PrusaConnect inherited from PrusaLink class with filled host address, disabled http diggest. After upload read header information - status message and pass it to notification and Printhost upload dialog via events, this message can be shown as warning notification and is recieved in localized lang. Pass accept-language shortcut in upload header. 3 option to upload. (upload, to queue, to print)
Upload Notification: Showing status text, changes in text, not showing close button, Completed state on special call (not 100%) and other design changes.
Right panel: Open URL button.
1) Fixed crack between the trimmed object triangles and the triangles
closing the cut (newly triangulated) by snapping the existing vertices
on cutting plane to coord_t scaled coordinates. Such snapping is
needed for vertices close to zero where float has a higher absolute
accuracy than coord_t.
2) Improved accuracy of triangle cutting by calculating the cut contour with doubles.
3) Improved accuracy of triangle cutting by implementing rounding to coord_t instead of floor.
