imgui_stdlib.h + imgui_stdlib.cpp
InputText() wrappers for C++ standard library (STL) type: std::string.
This is also an example of how you may wrap your own similar types.
imgui_scoped.h
[Experimental, not currently in main repository]
Additional header file with some RAII-style wrappers for common Dear ImGui functions.
