Boost Voronoi diagram produced degenerated Voronoi diagram. This Voronoi diagram was detected by our method for detection of those types of degeneration. But rotation by PI / 6 wasn't able to fix it.
So now, when the Voronoi diagram is still degenerated after the first rotation, then we try another rotation by different angles to fix the degenerated Voronoi diagram.
{if condition then block elsif}
The "then" keyword is now mandatory.
On the other hand, "then" keyword must NOT be used using old syntax:
{if condition}...{endif}
{if cond1}{expr1}{elsif cond2}{expr2}{else}{expr3}{endif}
could be written as
{if cond1;expr1;elsif cond2;expr2;else;expr3;endif}
the first semicolon after else is not manadtory, thus the following is valid
{if cond1;expr1;elsif cond2;expr2;else expr3;endif}
each expression could be also empty or contain multiple expressions:
{if cond1;elsif cond2;else endif}
Implements #4048#7196
Syntax:
(global|local) variable_name =
(scalar_expression|vector_variable|array_expr|initializer_list)
array_expr := array(repeat, value)
initializer_list := (value, value, value, ...)
The type of the newly created variable is defined by the type
of the right hand side intitializer.
Newly declared variable must not override an existing variable.
Variable may be assigned with global|local expression, but its type
must not be changed.
Newly the assignment operator also accepts the same right hand expressions
as the global|local variable definition.
1st parameter is the text to match against,
the rest of the parameters are pattern to be matched:
either strings, then the match is exact,
or regex enclosed in //
or regex string starting with ~
For example
one_of("a", "a", "b")
finds a in "a", "b"
one_of("abc", /.*a.*/)
matches "abc" using regular expression /.*a.*/
1) Implemented access to coEnum values, they are returned as strings.
2) Fixed some possible memory leaks.
3) Fixed some possible union type punning issues.
1) Flipped the order of "discover_vertical_shells" and "process_external_surfaces",
now the external surfaces are expanded after "discover_vertical_shells"
aka "ensure vertical wall thickness" is solved.
2) Reworked LayerRegion::process_external_surfaces() to only expand into
"ensure vertical wall thickness" regions, also the expansion is done
in small steps to avoid overflowing into neighbor regions.

Utility functions reserve_more(), reserve_power_of_2(), reserve_more_power_of_2()
Various SurfaceCollecion::filter_xxx() modified to accept an initializer list of surface types.
New bridges detector refactored to accept overhang boundaries.
BoundingBoxWrapper was moved from RetractCrossingPerimeters to AABBTreeIndirect.
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)
