(#6503) +- Clipper: Rework inner logic to allow functioning with a zero-clear constructor. + This is order to facilitate usage for language bindings (e.g cimgui or dear_binding) + where user may not be callinga constructor manually. (#5856) - Debug Tools: Added 'io.ConfigDebugIniSettings' option to save .ini data with extra comments. Currently mainly for inspecting Docking .ini data, but makes saving slower. - Backends: OpenGL3: Fixed support for glBindSampler() backup/restore on ES3.
