Implements a reusable pattern for generating executable thunks that redirect C++ virtual method calls to flat C functions. Uses VirtualAlloc with PAGE_EXECUTE_READWRITE to create thunks at runtime, supporting both x86 and x86_64. This is a non-obvious technique for Wine compatibility layers and could be extracted for other projects needing dynamic interface wrapping.

Provides a conversion_context struct that implements a two-level bump-pointer allocator for temporary allocations during API translation. Uses a fixed-size stack buffer with fallback to heap-allocated list entries. This pattern is clean, self-contained, and reusable in any project that needs efficient temporary memory for struct conversions.

A Python script that auto-generates the thunk C++ files (cppISteam*.cpp) from Steamworks SDK headers. It parses interface definitions and produces the boilerplate for calling Unix-side implementations. This pattern is reusable for generating Wine thunks for any COM-like API, and the script is well-structured with clear separation of concerns.

Manual implementation of VR render model loading that uses C++ templates to handle multiple interface versions with the same logic. Demonstrates a clean pattern for versioned interface dispatch without code duplication. The template-based marshalling of parameters is a reusable technique for similar compatibility layers.
