Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix the rendering color channels to be premultiplied with the alpha channel as thats what Xrender expects. Small fixes in X11_CreateTexture. Add some new functions in SDL_x11sym.h as well as support for Xrender.
