Dear Imgui with Signed Distance Fonts

[Flix01]

I've made a basic attempt to develop a SDF generator for Dear ImGui.

Despite the horrible quality of the fonts I was able to generate, I've discovered that it can be done without any changes to the internal code (and minimal changes to the binding file, e.g. imgui_impl_glfw.cpp)!

If somebody's interested, here is a gist I've made.

I still have to understand if signed distance fonts for ImGui are a good thing or not... 🤕

I've ended up updating the gist to use the same approach used by freetype-gl.
It's more robust and works pretty well.

Other issues that might be interested: #745 and #618.

[Edit:] Added this .gif (but its scaling makes it look a bit blurrier than normal 😞):

Closing this. It was not a real issue...
