Avoid naming collision with imgui_demo.cpp's HelpMarker() for unity builds.

Reserve space for a number of vertices and indices. You must finish filling your reserved data before calling PrimReserve() again, as it may reallocat

Helpers to retrieve ImRect (we don't need to store BuildWorkRect as every access tend to change it, hence the code asymmetry)

Known size hash It is ok to call ImHashData on a string with known length but the ### operator won't be supported. FIXME-OPT: Replace with e.g. FNV1a

It is the map we need iterate to find valid items, since we don't have "alive" storage anywhere

Public API to manipulate UTF-8 text We expose UTF-8 to the user (unlike the STB_TEXTEDIT_* functions which are manipulating wchar) FIXME: The existenc

Test that key is either not owned, either owned by 'owner_id'

Note that shortcuts are currently provided for display only (future version will add explicit flags to BeginMenu() to request processing shortcuts)

move cursor to first character of selection

Parse display precision back from the display format string FIXME: This is still used by some navigation code path to infer a minimum tweak step, but

Return false to discard a character.

Resize a vector to a smaller size, guaranteed not to cause a reallocation
