This fixes #868. It also fixes an issue I was seeing where the scaling factor set in the OS was being rounded to the nearest integer factor (e.g. I use a 165% scaling factor, but ngscopeclient was rendering at 200%).
Dear ImGui added native support for DPI scaling in release 1.92 (June 2025). See their new FAQ entry on DPI handling. That feature is still experimental and so it could break on future ImGui updates, but it seems to work much better than what we were doing before.
It looks like the ImGUI GLFW backend already has the necessary conditionals to disable scaling on macOS, so I didn't disable the DPI awareness settings on that platform like we did before.
