Here are all the changes i made, if you find something useful in there. Some things you may need to change, like screen refresh time that i have set at 30 sec in uiloop.cpp, (the ui was slow for me with high res rendering on CPU only).
Another thing the default render resolution, that ui starts up with in uiloop.cpp, i have it 6000 x 4500 pix.
And at what resolution ui window loads up with in uiloop.cpp, for my screen 3840x2160 with windows font dpi scale 250%, i use windowWidth = 3823 and windowHeight = 1920.
You may need to scale down font size in imgui_impl_glfw.cpp for smaller screen, it's at 42.
Here is fresh windows opencl build for test run, don't use it for production, i made some other changes for testing core features:
