       For more advanced uses, you may want to read from:
        - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
        - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
        - or query focus information with e.g. IsWindowFocused(), IsItemFocused() etc. functions.
       Please reach out if you think the game vs navigation input sharing could be improved.

+      Enabling ImGuiConfigFlags_NavMoveMouse instructs dear imgui to move your mouse cursor along with navigation movements.
       When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantMoveMouse' to notify you that it wants the mouse cursor to be moved.
       When that happens your back-end NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the binding in examples/ do that.

        to set a boolean to ignore your other external mouse positions until the external source is moved again.)

                      - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
                      - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
