feat(ui): imgui 1.91.9b-docking in place of 1.73: local changes of the backends carried over (glad as the gl loader, srgb and gamma of the ui, gles glsl string), BufferingBar/Spinner kept, imgui_tables in cmake; cursor position, cursor enter and focus of the main window passed to the glfw backend, which works with events now; code adapted to the api: ImGuiListClipper::Begin, BeginListBox, ImTextureID as an integer, ImageButton with an id, ImGuiKey without GetKeyIndex, logarithmic sliders in place of the removed power argument; ImGuizmo with the math operators defined before imgui.h and SetNextFrameWantCaptureMouse
