I already had an official copy of the imgui library in my program and when I added imgui-node-editor, I get this build error when my codebase references the official imgui.h:

'_FringeScale': is not a member of 'ImDrawList'

The following commit added _FringeScale to ThirdParty/imgui/imgui.h:
11d2dca

However, I don't see any reference to it in the official imgui repo:
https://github.com/ocornut/imgui

This customization to imgui means I have to use your custom version of imgui throughout my codebase. Even when I built imgui-node-editor, other libraries in my codebase would reference the official imgui.h, which doesn't have _FringeScale. I suggest contributing this change and any other customizations to the imgui project and only consume them once they are merged to master.

If you really want a custom imgui, please rename the source and the public interfaces so that it can coexist with the official imgui library.
