2.4 roadmap

B sparse infill should follow polys between intersect points
B expand > 0 producing artifacts with manual supports
B fix adaptive slicing with multi-extruder
B fix supports with grouped parts
B multi-extruder rendering of raft fails to offset the rest of the print
B multi-extruder purge blocks fail to generate properly for rafts
F control layer start position
F redo auto supports to use poly faces rather than deltas
F control for size of purge block (with 0=disabled)
F add separate fill speed control
F polishing and other non-planar work
F gradient infill https://www.youtube.com/watch?v=hq53gsYREHU&feature=emb_logo
F feather sharp tips by reducing extrusion in area of overlap
F first layer segment large flat areas for better fill reliability
F enable purge blocks when quick layers are detected
F apply finish speed to exposed top and underside flat areas
F expand internal supporting flats
F first layer support speed should be same as shell speed
F trim support offset from layer below
F option to support interior bridges when 0% infill
F calculate filament use per extruder per print
P implement infill clipping in wasm
P solid fill the tops of supports for down facing flats

P prioritize supports by length of unsupported span. mandatory when circularity > X

or % area of inner to outer poly is high (making it a thin shell)

B fix multiple tab heights in contouring (uses highest now)
B climb vs conventional not fully consistent after refactor
B outside cutting direction in roughing mode inverted
B clear voids has double interior pass because wrong offset shadow used
B top clearing operations should use linear, not offset, passes
F switch z top offset to an z anchor (top/bottom) + offset
F use 3 registration holes to prevent rotation accidents (midline offset one axis)
F parameterize dropping close points in prep.js. ensure long segments remain straight
F flat and volumetric rendering of paths
F z bounded slices (extension of z bottom offset feature)
F z planar settings visualizations
F use arcs to connect acute angles
F extend acute roughing on inside polys to clear small voids
F lead-in milling
F adaptive clearing in roughing mode
F trapezoidal tabs (in the Z axis)
F ease-in and ease-out especially on tab cut-out start/stop
F implement z line-only follows for ball/taper
F add option to spiral in vs out (optimal tool life) vs mixed (optimal path)
F add support for tapered ball mills
F warn when part > stock or cuts go outside bed
F A-B linked cutting profiles for double-sided milling / part flips
P crossing open space check point is outside camshell before returning max z
P detect render message backlog and pause or warn
