Why is it that often when you ask for help you go back and stumble on the solution yourself...
I found doing this, and then using mmdraw->AddLine() (etc) does the job for me ( the various offsets I have to adjust to follow the window but the drawing is rendered on the new window canvas and appropriately clipped ).
ImGui::SetNextWindowSize(ImVec2(mm_board_width *1.2, mm_board_height *2.2), ImGuiCond_FirstUseEver);
ImGui::Begin("Another Window");
ImVec2 canvas = ImGui::GetWindowSize();
ImDrawList *mmdraw = ImGui::GetWindowDrawList();
...
...
ImGui::End();

Details:
Simply put, I want to draw a mini-map ( bottom right corner of screen shot ) within the ImGui moveable / resizeable window.
Currently I am drawning the minimap as part of the main draw-> process for the rest of the visible circuit board, and the drawlist is then rendered, all good. I would however like to make it instead that the minimap is drawn within the moveable "Another Window".
I have been searching around at various tutes/guides but haven't been able to quite grok what I'm doing.
I'm not using any OpenGL primatives; this is all SDL2 software rendering, everything is drawn directly to screen coordinate space.
The minimap drawing process is a single function self-contained..
Apologies if these seems like a stupid/trivial question; you'd think after years of writing this codebase I'd have expanded more in to other ImGui features/understandings.
