* [FEATURE] Experimental small area flow compensation This is a native implementation of the [Small Area Flow Compensation](https://github.com/Alexander-T-Moss/Small-Area-Flow-Comp) post-processor by Alexander Þór for OrcaSlicer. Quite often small areas of solid infill appear to be over-extruded, despite the rest of a print looking like it has a well-dialled-in EM/Flow. Currently, there isn't a good understanding of why this happens, so this is an attempt at a brute-force approach to treat the symptom. This feature modifies the flow of extrusion lines inversely proportional to the length of the extrusion line (the shorter the extrusion, the less flow it should have). Alexander Þór: Author of the original script implementation Weaslus: Proof Reader, Hypeman & pestered folks into making this * [TASK] Whitespace cleanup * [TASK] Add credits, format code, improve input labels * [TASK] Use multi-line textbox as input for flow model * [TASK] Toggle flow compensation per object * [TASK] Enable flow compensation for first layer --------- Co-authored-by: SoftFever <softfeverever@gmail.com>
