- if you want to use a different font than the default
- create bitmap font data using BMFont. allocate ImGui::GetIO().Font and use ->LoadFromFile()/LoadFromMemory(), set ImGui::GetIO().FontHeight
- load your texture yourself. texture *MUST* have white pixel at UV coordinate 'IMDRAW_TEX_UV_FOR_WHITE' (you can #define it in imconfig.h), this is used by solid objects.

- tip: the construct 'if (IMGUI_ONCE_UPON_A_FRAME)' will evaluate to true only once a frame, you can use it to add custom UI in the middle of a deep nested inner loop in your code.
- tip: you can call Render() multiple times (e.g for VR renders), up to you to communicate the extra state to your RenderDrawListFn function.
