Multi view here about imguizmo HOT 3 OPEN

I had to do much the same to avoid the gizmo stretching strangely when resizing panels. x, y, w, h all need to correspond to the pane, not the window to work properly in a multi-panel UI.

I second the vote to have an API for this.

I'm a bit overwhelm at the moment but you can submit a PR with the modifications

Here you go ~ it's my interpretation of what @volcoma said in the original post. I call SetRect just before Manipulate. #23

e.g.

			auto origin = gui::GetItemRectMin();
			auto sz = gui::GetItemRectSize();
			ImGuizmo::SetRect(origin.x, origin.y, sz.x, sz.y);
                        ...
                        ImGuizmo::Manipulate(...

(PS, and thanks again for your lovely library :) )
