// PushClipRect Clipping
// - Mouse hovering is affected by ImGui::PushClipRect() calls, unlike direct calls to ImDrawList::PushClipRect() which are render only.
// 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 called functions which to modify both channels and clipping simultaneously tend to use the
//     more specialized SetWindowClipRectBeforeSetChannel() to avoid extraneous updates of underlying ImDrawCmds.
