A regression error has been introduced into Slic3r 1.38.xx series
for the float/percent config value, where the value was considered
unchanged if the percent sign has been added or removed.
the point type on Windows / Linux / OSX
to achieve the same behavior on all the 32 / 64bit systems.
(Windows always treats the long as 32bit int, while Linux treats
long as a 64bit int).
The problem was caused by the gap fill algorithm, which worked
with square extrusion width values as with rounded extrusion widths,
which sometimes lead to negative extrusion cross sections
for high height to width ratios.
The extrusion width logic has been changed to consider the input width
to be the extrusion spacing, not the extrusion width. The change certainly
removed the negative feed rates, but it also certainly increased the gap
fill width to some exent. It needs to be verified now, whether the gap fill
does not extrude too much.

Added some functions to TabIface.
Added BedShapeDialog & Bed2D classes.
Added new_scale to Polygon.
In class Field: Point renamed to PointCtrl and added set_value for PointCtrl, extended get_value for Choice.
The previous way of checking that _putenv_s is defined does not work,
because _putenv_s is a function and not a define. This is a partial
application of commit 31115e0369747b1e1c45cbe3f2a90f6dff66666a from
alexrj/Slic3r.
I tried cherry picking the whole commit, but unicode is already handled
diffrently here, so that would have been a lot of work.
due to the differences in the M203 code
(RepRap firmware has it in mm/min, Marlin in mm/sec).
This difference is important to the G-code time estimator.
Changed the g-code flavor to Marlin for all Prusa3D bundled profiles.

The "Send to OctoPrint" function will now send the file name encoded
in UTF-8, so the file name will not get mangled.
The C++ Slic3r::encode_path() function was returning a string to Perl,
which was marked as UTF-8. This has been fixed, now encode_path() returns
a plain Perl string.
Added path_to_filename, path_to_stem, path_to_extension, path_to_parent_path
Perl wrappers to boost::filesystem::path splitting functionality
to be able to split UTF-8 encoded files on Windows correctly.
at the placeholder parser.
Implemented a new PlaceholderParser::evaluate_boolean_expression()
functionality to evaluate just a boolean expression using the full
expressive power of the macro processing syntax. This function
will now be used for deciding, which print or filament preset
is compatible with which printer preset.
in a form similar to Perl:
Following expression returns true, if the variable matches the regex:
variable =~ /regex/
Following expression returns true, if the variable does not match the regex:
variable !~ /regex/
The Clipper library is not stable when calcuating offsets of contours
with holes. Replaced a single call of offset2 with offset_ex(offset_ex()).
This is not the most efficient solution, but it fixes this problem.

"Multimaterial printer switches filament at the wrong time during a print"
https://github.com/prusa3d/Slic3r/issues/607
There was a single layer between the raft top and the object first layer
missing on the wipe tower, and after this missing layer all the tool
changes were shifted by one layer, meaning two color print had the colors
switched.
bundled with Slic3r installation, and install it into user's Slic3r profile.
These bundled config bundles will be contained in the Slic3r source
tree under Slic3r/resources/profiles.
Breaking change! The Slic3r user directory has been renamed to Slic3rPE
for the Prusa Edition. Also it is likely, that the Slic3rPE directory
will be reorganized before the final 1.38 release to reserve space
for temporary profiles downloaded from the Internet.
The PlaceholderParser is currently used by the GCode.cpp
and by Printer.cpp to generate a new name for the exported G-code or SVG file.
The PlaceholderParser::process() will throw a runtime_error with
a comprehensive error message.
The G-code export will include these error messages into the G-code text
with !!!!!! separators, and the GUI will inform the user, that the G-code
export failed.
both single_extruder_multi_material and wipe_tower are enabled,
and the print prints with a single extruder only.
Newly the same situation will be handled through a conditional G-code
in the following format:
{if not has_wipe_tower}
; Do the priming
{endif}
fixed crashes when loading a config.ini with "compatible_printers"
disabled export of "compatible_printers" into gcode and config.ini
Enabled compatibility of printing multiple objects with support / no support
with a wipe tower.
gap created between the support and the support sheath.
Now the support sheath will overlap with the support base by 10%
of the extrusion width by default.
G-codes in case of single extruder multiple material setup:
At the start of the print, the filament_gcode_start is executed
for the active extruder only, and the filament_gcode_start /
filament_gcode_end are then executed at each tool change.
When the Prusa MM wipe tower is active, the tool changes are handled
a bit differently: M900 K0 is emited before the wipe tower extrusions start,
and the filament_gcode_start code is executed after the wipe tower extrusions
are done. This rule effectively disables the linear advance over the wipe tower.

Improved handling of custom G-code blocks: Slic3r will try to extract
the target extruder and bed temperatures from the custom G-code blocks.
Removed Perl Flow::new_from_spacing bindings.
Some Fill C++11 beautification.
Fix of a support_material_1st_layer_flow, brim_flow and skirt_flow logic to use the extrusion_width if both first_layer_extrusion_width and support_material_extrusion_width are undefined.
Documented the extrusion width logic in the config tooltips, including the default values.
The values of StaticPrintConfig derived objects were searched by a name
walking through a huge chained if.
Now they are being mapped with a std::map.
Also initialization of StaticPrintConfig classes from their ConfigOptionDef
defaults is done by maintaining a single global definition of each
StaticPrintConfig derived class, and a new instance is initialized
from this static copy.
Also the ConfigOption instances are casted using static_cast
wherever possible, and their types are verified by a virtual type() method.
This approach avoids insiginificant performance penalty of a dynamic_cast.
Also the compare and clone methods were added to ConfigOption,
and the cloning & compare work on binary values, not by serialization.
discover_horizontal_shells() fron Perl to C++, where
the already calculated bridge direction was being lost.
Improved constness of the debug methods

void export_region_fill_surfaces_to_svg(const char *path) const;
cleanly on Windows & Linux. There is still a work on OSX:
The XS module has to be linked without perl.lib and with
the following parameters to produce a bundle: -bundle -undefined dynamic_lookup
merged "Use submenus for listing options in dropdown menu." #3905
thanks @alexrj
Adapted the "Use submenus" code to sort the menus in the same order
as they appear in the parameter tabs.
Removed the Perl dependencies on Encode, Encode::Locale and Unicode::Normalize.
Added dependency on boost::locale.
Added encode_path, decode_path, normalize_utf8 functions to Slic3r.xs
Slic3r.xs has been made mostly utf8 safe by using the boost::nowide library,
thanks to @alexrj for the idea.
Simplified the encode_path / decode_path stuff:
wxWidgets are unicode already, so there is no need to decode_path() from it.
Perl / win32 interfacing is non-unicode, so decode_path() is executed
on ARGV just at the beginning of the perl scripts.

The bridging angle override may be set at the Infill->Advanced settings,
or through a modifier mesh.

Change of the PlaceholderParser:
All vector configuration values stored into the PlaceholderParser
are expected to be addressed by the extruder ID, therefore
if a vector configuration value is addressed without an index,
a current extruder ID is used.
Also a small fix of fan handling: The fan speed is set to zero
at the start of the G-code if the cooling for the initial extruder
is disabled.
Added UNUSED macro to libslic3r.h, used it to reduce some compile warnings.
Split the Int128 class from Clipper library to a separate file,
extended Int128 with intrinsic types wherever possible for performance,
added new geometric predicates.
Added a draft of new FillRectilinear3, which should reduce overfill near the perimeters in the future.
1x nozzle_dmr for support and top infill,
and 1.125x nozzle_dmr for the rest.
This corresponds roughly to the default values tuned for the Prusa MK2
for normal prints.
Added an "overlap" member variable to fill classes in the preparation
for futher move of the "infill / perimeter" overlap to the Fill class.
Moved the orientation predicates from Fill to Geometry.
