Conditional G-code and arithmetic expressions parser

Language: C++ Difficulty: Easy-Medium

Implement a parser for conditional and arithmetic expressions within custom G-code. #3390

Port the GUI to C++

Language: C++ Difficulty: Easy

The GUI is coded in Perl using wxWidgets. The wxWidgets API is almost identical between Perl and C++. There are a couple things where we use the dynamic features of Perl which are trickier and interesting to port in C++.

Wireframe printing

Language: C++ Difficulty: Medium

Implement the wireframe printing algorithm. #2274

---

Automatic part rotation

Refactor the TriangleMesh class and support non-solid walls

Language: C++ Difficulty: Medium/Hard

Replace the internal mesh representation (currently based on admesh) using an existing 3D mesh library or implementing a half-edge structure; only use admesh for fixing models. Keep non-solid walls and slice them as single paths. #3560 #3523

Implement 3MF format read/write

Language: C++ Difficulty: Easy

Add the 3MF format for both reading and writing. #2811
