Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
SDL_PushEvent() calls the event filter code, and has a return value to tell whether or not the event was actually pushed. SDL_GetEventFilter() now returns an SDL_bool instead of the filter function.
