As 1) user is unlikely to store that on their end. 2) nowadays with lambdas isn't an easy user-side conversion.
Then we limit explosion of an already messy API.
Didn't convert Combo() "const char* items_separated_by_zeros" as this doesn't translate well when used via a ImStrv constructor, may actually aim to obsolete.
It's widely incomplete and slow, requires a printf function taking non-zero-terminated format string to work.
Might do it eventually but it's much less a problem than labels. Format string are more frequently inlined in code and tend to be small, so existing solutions at call site can work better for now.
Squashed commits (initially a commit from rokups + many rework by ocornut. keeping them separate commits made rebasing unnecessarily tricking so merged from 2024/02)
ImStrv: many fixes (see details), added imconfig class extension example, added natvis description.
ImStrv: rework toward ensuring End is always set to constant can be compile time calculated
ImStrv: using length(), fix ambiguous empty() function, fix altered behaviors, removed unused operators.
ImStrv: various tweaks and fixes. removed ImGuiTextRange from ImGuiTextFilter, fix test engine hooks, removed constructor only used twice.
