Some of our basic changes remained, but a lot of work still needs to be done. At least it builds though! I have a few notes off the top of my head writing this: - Our build system was kept and modified to work with the new codebase. Similarly, the codebase was modified to work with our build system. - We don't support Audacity's full wxBase restrictions, so I just replaced it with wxWidgets::wxWidgets for now. (See above). - There are still networking features, which are to be removed in the next commit. - pffft was added as a library in lib-src, and I wrote a new CMakeLists.txt for it. - I modified WrapAllegro.h to use our allegro.h shim instead.
