Check for GCC version >=4.7 [covers GCC or, theoretically, Intel C Compiler] or __has_builtin(__atomic_add_fetch) [covers Clang]. If either of these are found, prefer the GCC atomic builtins instead of the C11 builtins.
Also: Gates Microsoft atomics on _MSC_VER, not _WIN32. This may help improve compatibility with mingw but has not been tested.
mat4_transform ignores the final row of the matrix, which normally contains scale data. This is fine for modelview matrices, which is all lovr currently uses mat4_transform for. However it fails if you ever use mat4_transform on a projection matrix.
mat4_transform_project takes the final row into account, so you can use it with projection matrices. This was useful in my fork and might be useful to have around in lovr someday later.
- Add t.hotkeys flag to conf.lua, which defaults to true.
- If t.hotkeys is truthy, the following hotkeys will be enabled:
- Escape: Quit the experience
- F5: Restart the experience
- Ref struct only stores refcount now and is more general.
- Proxy stores a hash of its type name instead of an enum.
- Variants store additional information instead of using a vtable.
- Remove the concept of superclasses from the API.
- Clean up some miscellaneous includes.
