Proprietary mesh triangulation in open source software?

Recently I was looking for a solid, reliable way to do path triangulation. Looking at state-of-the-art research, I came across the UC Berkley researcher Jonathan Shewchuk's outstanding Triangle library.

Jonathan is very clear on the Triangle website, and in source code, about the project not being open-source:

This program may be freely redistributed under the condition that the copyright notices (including this entire header and the copyright notice printed when the `-h' switch is selected) are not removed, and no compensation is received. Private, research, and institutional use is free.

Because cross-compiling binaries for Windows is easier than building natively

I want Microsoft to do better, want Windows to be a decent development platform-and yet, I constantly see Microsoft playing the open source game: advertising how open-source and developer friendly they are - only to crush developers under the heel of the corporate behemoth's boot.

The people who work at Microsoft are amazing, kind, talented individuals. This is aimed at the company's leadership, who I feel has on many occassions crushed myself and other developers under. It's a plea for help.

The source of truth for the 'open source' C#, C++, Rust, and other Windows SDKs is proprietary

You probably haven't heard of it before, but if you've ever used win32 API bindings in C#, C++, Rust, or other languages, odds are they were generated from a repository called microsoft/win32metadata.

WIDL compiler incompatibilities with Windows SDK

I attempted to compile the IDL files distributed in https://github.com/microsoft/win32metadata/tree/master/generation/WinSDK/RecompiledIdlHeaders using the latest (7.0.1-rc.1) version of the Wine IDL compiler, called WIDL. Unlike Microsoft's MIDL compiler which ships with Visual Studio, WIDL is open source.

More importantly, WIDL contains patches to generated header files that make e.g. COM calling conventions compatible with mingw-w64 and clang when targetting GNU ABI.

Bugs
- Imports are incorrectly case sensitive
- WIDL does not allow double slashes in string literals
Segmentation faults
