This is similar to an ExtrusionLoop, but it is open.
It may contain multiple chained paths with differing parameters.
This allows one to have a hierarchy of paths, where the ExtrusionEntityCollection
will be chained by the G-code generator, but ExtrusionMultiPath will not.
inside ClipperUtils are now using bit shifts instead of multiplication
by doubles, which makes the scaling precise.
Removed the scale parameter from all offset functions.
Modified the safety offset to calculate offset per polygon instead
of over all polygons at once. The old way was not safe and very slow,
sometimes this meant a kiss of death for supports for example.
Crashes while switching in preview through layers with arrow keys
Also added a check box to visualize a single layer only
in the 3D path view. The check box may be toggled with a 'S' key.
Added shift+U / shift+D buttons in the 3D path view to show a single
layer only.
Replaced eval { die } construct with a bool return value indicating
success or failure of an automatic arrangement of parts on the print bed.
Don't know exactly what is happening here, but throwing a "die" inside
a XS function and then catching it inside an eval {} block is suspcious.
Added "filament_max_volumetric_speed", a cap on the maximum volumetric
extrusion role, filament specific. This is very useful when mixing
rigid filament with a soft filament.
Extended the import / export of multi-string values into configuration
values, including the test cases. Multi-line strings will be enclosed
into quotes, quotes escaped using a C-style escape sequences. Single
word strings could still be stored without quotes.
if there is any valid option available. This feature has been asked for
by the Prusa3D customers as the '- default -' option has nothing to do
with the actual printer and when selected accidentally, it could even
lead to a printer damage.
Removed the deprecated VibrationLimit feature.
Added triangle infill.
The Prusa3D fork of Slic3r has been marked as "Slic3r Prusa Edition"
with menus pointing to the prusa3d/slic3r github release page
and Prusa3D drivers downloads page.
Also a bug has been fixed for zero interface layers. Before
slic3r would put infinite number of interface layers over top surfaces,
if the number of interface layers was set to zero.
