Method ChannelsSplit

extern/imgui/imgui.h:2699–2699

Advanced: Channels - Use to split render into layers. By switching channels to can render out-of-order (e.g. submit FG primitives before BG primitives) - Use to minimize draw calls (e.g. if going back-and-forth between multiple clipping rectangles, prefer to append into separate channels then merge at the end) - FIXME-OBSOLETE: This API shouldn't have been in ImDrawList in the first place! Prefer

    //   Prefer using your own persistent instance of ImDrawListSplitter as you can stack them.
    //   Using the ImDrawList::ChannelsXXXX you cannot stack a split over another.
