Rendering the git graph on the server means that we can properly track flows and switch from the Canvas implementation to a SVG implementation. * This implementation provides a 16 limited color selection * The uniqued color numbers are also provided * And there is also a monochrome version *In addition is a hover highlight that allows users to highlight commits on the same flow. Closes #12209 Signed-off-by: Andrew Thornton art27@cantab.net Co-authored-by: silverwind <me@silverwind.io>
