* Fix support interface semantics and gap handling Fix zero-gap interface detection and gap initialization for supports and raft. Ensures correct top/bottom contact semantics and avoids relying on default zero gaps. * Additional fixes and robustness improvements Fix incorrect coupling between top and bottom support interface spacing and density, ensuring bottom interfaces use their own parameters for smoothing and toolpath generation. Restore correct bottom interface generation for organic (tree) supports when a non-zero bottom Z gap is used, and preserve contacts even when base polygons are empty. Improve robustness of organic support slicing by fixing layer index drift and guarding against degenerate polygon boolean operations. * Typo and semantics fix differnt_support_interface_filament -> different_support_interface_filament soluble -> zero_top_z_gap * Fix non organic tree bottom support interface generation Slim tree bottom interface layer numbers were capped by the object's layer number beneath it. Fixed by refactoring the generation algorithm. * Fix non organic tree interlaced support generation Deterministic local interlaced support layers generation for non-organic tree support * Enable support interface multimaterial for non organic tree Enables mixed-material support interface behavior for non organic tree support type. * Fix tree support interface layer counts and contact handling - Correct non‑organic tree top interface layer budgeting so gaps don’t consume a layer (N stays N). - Remove the extra roof interface pass that was duplicating the 2nd layer. - Organic tree: use only the lowest contact footprint and avoid extra bottom‑contact extrusion so interface count matches the user setting. * Bugfixes (a lot) Many, many bugs fixed, majority edge-case but still not playing by the rule. Some of them: - on multilevel base, on very small level variations the support was capped to the topmost level height - non-organic tree had gaps for supports in a multilevel base situiation - independent support layer height had issues with support interfaces (base support beneath bottom interface, top contact layer sometimes missing) - organic tree had issues with small variation multi-level base - organic tree support with zero top Z distance could overlap support-material and interface-material paths when separate materials were used - many, many others (I lost track of them)
