Guaranteed to honor 'num_segments'

Current score encoding (lower is highest priority): - 0: ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverActive - 1: ImGuiInputFlags_Active

Helper to snap on edges when aiming at an item very close to the edge, So the difference between WindowPadding and ItemSpacing will be in the visible

Advanced: Channels - Use to split render into layers. By switching channels to can render out-of-order (e.g. submit FG primitives before BG primitives

Zero-clear except IO as we preserve IO.Requests[] buffer allocation.

Demonstrate old/legacy Columns API! [2020: Columns are under-featured and not maintained. Prefer using the more flexible and powerful BeginTable() API

Closely mimics PathBezierToCasteljau() in imgui_draw.cpp

Those functions are designed to facilitate changing the underlying structures for ImFontAtlas to store an array of ImDrawListSharedData

FIXME: Code is duplicated with code above.

FIXME-OPT: This is not a fast query. Adding a BakedCount field in Font might allow to take a shortcut for the most common case.
