the amount of total extruded material and per extruder extruded material
up to the point the value is evaluated:
"extruded_volume", "extruded_weight",
"extruded_volume_total", "extruded_weight_total"
Newly each custom G-code block may exchange the following values with slicer:
Position and Z-hop:
position (read/write)- 3 element vector (X, Y, Z) of current G-code position. Z element contains the current Z hop.
zhop (read only)- initial zhop value
Extruders: vector variables, one element per extruder:
e_position (read/write) - absolute E position, only available with absolute extruder addressing
e_retracted (read/write) - current retraction state
e_restart_extra (read/write) - current planned extra deretraction when starting printing
For readibility, script's if / elsif / else / endif syntax was modified:
{if cond then
block
elsif cond then
block
else
block
endif}
Semicolon is not required after else or endif.
- remove the infinite skirt
- added 'idle_temperature' in Filament Settings as an optional parameter
- the logic is changed: if idle_temp is present, it is used,
otherwise it uses the old delta value from Print Settings
- TODO: the optional parameter is not well supported in UI

Based on the unfinished idea of @supermerill, defining ExtrusionRole
as a bit mask of ExtrusionRoleModifier.
Because the ExtrusionRole was used for both ExtrusionEntity and
G-code export / G-code viewer, the original ExtrusionRole had to be split
to ExtrusionRole and GCodeExtrusionRole to support bitmask attributes
for the former while keeing a low number of ordinary values for the latter.
New step - estimation of curling on both the model and the support extrusions.
Improvements in curled filament estimation algortihm
Implementation of Jump Point Search algorithm
Use of JPS algorithm to avoid curled extrusions during travel moves in Gcode export
of Layer->LayerSlice->LayerIsland hierarchy. This should improve
tool path ordering of multiple parts within the same object #5511.
Some shells tests rewritten from Perl to C++.
FIXME: Gap fill extrusions are currently not handled by the initial
G-code preview!

Replacing a homebrew const pointer wrapper const correctness helper
with the C++20 like span library.
One day when we switch to C++20 we will just use the C++20 spans instead.

Now pressure equalizer is returning one layer back (the previous layer).
GCode produced by pressure equalizer now has the same number of decimal places as non-processed GCode.
Pressure equalizer was disabled for external perimeters and gap-fill.
circular, convex, concave) and performs efficient collision detection agains these build
volumes. As of now, collision detection is performed against a convex
hull of a concave build volume for efficency.
GCodeProcessor::Result renamed out of GCodeProcessor to GCodeProcessorResult,
so it could be forward declared.
Plater newly exports BuildVolume, not Bed3D. Bed3D is a rendering class,
while BuildVolume is a purely geometric class.
Reduced usage of global wxGetApp, the Bed3D is passed as a parameter
to View3D/Preview/GLCanvas.
Convex hull code was extracted from Geometry.cpp/hpp to Geometry/ConvexHulll.cpp,hpp.
New test inside_convex_polygon().
New efficent point inside polygon test: Decompose convex hull
to bottom / top parts and use the decomposition to detect point inside
a convex polygon in O(log n). decompose_convex_polygon_top_bottom(),
inside_convex_polygon().
New Circle constructing functions: circle_ransac() and circle_taubin_newton().
New polygon_is_convex() test with unit tests.
WIP to G-code export parallelization through pipelining:
GCodeProcessor is called during the G-code export,
the G-code is no more reopened and re-read, but it is pipelined
from the G-code generator.
object layer over raft interface:
"first_layer_speed_over_raft", "first_layer_acceleration_over_raft".
Fixes I have a question about the speed of the first layer after the raft. #6623
Fixes Layer After Raft Is Not Considered First Layer! #6166
1) If "support on build plate only" is enabled, the support columns are
newly trimmed to not land on top of an object. However this may make
the column too small to be stable.
2) Support enforcers newly take precedence over "supports on build plate only"
and over "don't support bridges".
3) Some refactoring of the support generator code for clarity: Reduced
some of the worst spagetti offenders.
Fixes Support generated even if support on build only activated #915
Fixes Bug: supports on build plate only #1340
Fixes Bottom interface layer is not generated , support on build plate only. (long open defect) #4199

Fixes Don't cancel support enforcers with "don't support bridges" #5105
The thread local storage variables for the random number generator
were replaced by an external context variable.
Thread local storage is a scarce resource.
1) The macro-processor sanitizes the source code line for invalid UTF-8
characters. Ideally these invalid characters would be replaced with ?,
they are just dropped as of now. Better than showing an empty string
when converting to wxString though.
2) G-code export collects full error message for 1st occurence of an error
for each custom G-code block.
3) The composite error message now displays the errors collected in 2).
4) The error window is now scaled bigger and the Slicer logo is smaller
if the text is to be rendered with monospaced font, as the monospaced
text will not be word wrapped.
In addition to an existing "layer_z" placeholder variable,
a new "max_layer_z" has been added to custom G-code sections accumulating
maximum of "layer_z" over the print. This value may be used for example
in the end G-code of a sequential print to lift the print head
up before travel over the whole print bed.
