Update WR (details below):

* Add support for clip masks on text runs. * Fix atomic ordering of items with multiple shadows. * Update to bincode + ipc-channel with optimizations. * Fix some plane splitting precision errors. * Improve the anti-aliasing quality significantly. * Add internal ClipChain support. * Fix diacritic glyphs on Linux.
