Method PushClipRect

src/imgui/imgui.cpp:5720–5725

Push a clipping rectangle for both ImGui logic (hit-testing etc.) and low-level ImDrawList rendering. - When using this function it is sane to ensure that float are perfectly rounded to integer values, so that e.g. (int)(max.x-min.x) in user's render produce correct result. - If the code here changes, may need to update code of functions like NextColumn() and PushColumnClipRect(): some frequently

// - This is analogous to PushFont()/PopFont() in the sense that are a mixing a global stack and a window stack,
//   which in the case of ClipRect is not so problematic but tends to be more restrictive for fonts.
