* Namespaces have been updated to reflect the move from //flutter/sky/shell to //flutter/shell. * shell/BUILD.gn file has been split into smaller GN files for each subcomponent of the shell (common, GPU, diagnostic, testing). * GN dependencies have been rewritten to stop exposing common shell dependencies as public. Duplicates have also been removed. * GPU subcomponent has been updated make it more suitable for Vulkan integration. * The GLFW backend has been resurrected.
