- Some compile options that make sense for build.bat, and a build_release.bat
- oogabooga:
- Big buffer program_memory that always has same base address (goodbye serialisation problems)
- Big buffer grows as needed, crash when out of memory
- Very sexy platform abstraction & basic os call procedures
- Heap allocator around the program memory.
- Jaiyfication (context, context.allocator, push_allocator, temp allocator)
- Some tests to make sure we ooga the right boogas
