// =============================================================================
// FEATURE: internal_separator_text — the imgui_internal.h separator / low-level
//          text primitives below the public Separator / Text API. Cherry-picked
//          into the v2 binding: SeparatorEx (raw, internal_allow_func — its
//          ImGuiSeparatorFlags binds as int, cast at the call site); TextEx
//          (nullable text_end) and SeparatorTextEx (nullable label_end) are manual
//          C++ wrappers (dasIMGUI.main.cpp) that pin the terminus to nullptr. New
//          internal enums ImGuiSeparatorFlags (Horizontal / Vertical / SpanAllColumns)
//          and ImGuiTextFlags (NoWidthForLargeClippedText). This is the "binding is
//          usable" gate: it drives the real bound API at runtime.
// SHOWS:   SeparatorEx with varying thickness + a vertical separator between
//          same-line items; TextEx (the low-level text renderer, with / without its
//          layout flag); and SeparatorTextEx — a separator carrying an inline label.
// STANDALONE: daslang.exe modules/dasImgui/examples/features/internal_separator_text.das
