Extract the format out of a format string with leading or trailing decorations fmt = "blah blah" -> return fmt fmt = "%.3f" -> return fmt fmt =

Trim str by offsetting contents when there's leading data + writing a \0 at the trailing position. We use this in situation where the cost is negligib

Find end-of-line. Return pointer will point to either first \n, either str_end.

API is designed this way to avoid exposing the 4K page size e.g. use with IsGlyphRangeUnused(0, 255)

[Optional] Notify the system of Tabs/Windows closure that happened outside the regular tab interface. If a tab has been closed programmatically (aka c

Closely mimics ImBezierCubicClosestPointCasteljau() in imgui.cpp

We don't use g.FontSize because the window may be != g.CurrentWidow.

Note: as with every ImDrawList drawing function, this expects that the font atlas texture is bound.

Sanitize format - Zero terminate so extra characters after format (e.g. "%f123") don't confuse atof/atoi - stb_sprintf.h supports several new modifier

To scale your entire UI (e.g. if you want your app to use High DPI or generally be DPI aware) you may use this helper function. Scaling the fonts is d

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

Demonstrate creating a window which gets auto-resized according to its content.
