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

// dear imgui: Renderer Backend for OpenGL2 (legacy OpenGL, fixed pipeline)
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
// Implemented features:
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
// [X] Renderer: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// Missing features or Issues:
// [ ] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset).
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
