Let the paint-server client compute and pass any additional transform

The clients/callers of updateGraphicsContext(...) already independently
compute the same transform as computeResourceSpaceTransform(...). This
means that we can get rid of the latter in favor of the computations in the
callers - who just need to set up an AffineTransform and pass to
updateGraphicsContext(...).
This allows getting rid of the ApplyToTextMode resource-mode flag, and
doing so allows converting the RenderSVGResourceMode enum to a non-bitmask
such - and remove RenderSVGResourceModeFlags.
