Class: EstimateTextMeasurer

Defined in: common/textmeasure.ts:304

Raw textspan_lut.c estimate: un-hinted per-char widths summed once, no kerning, height = fontsize * LINESPACING. Reproduces graphviz's HEADLESS measurement (no textlayout plugin → estimate_textspan_size) exactly, making it the deterministic, font-stack-independent reference for layout-rules validation. Unlike LutTextMeasurer this does NOT apply per-char FreeType px hinting.
