Helper to calculate coarse clipping of large list of evenly sized items. NB: Prefer using the ImGuiListClipper higher-level helper if you can! Read co

Calculate text size. Text can be multi-line. Optionally ignore text after a ## marker. CalcTextSize("") should return ImVec2(0.0f, g.FontSize)

Simple version, may lead to an inverted rectangle, which is fine for Contains/Overlaps test but not for display.

User can input math operators (e.g. +100) to edit a numerical values. NB: This is _not_ a full expression evaluator. We should probably add one and re
