Subject: Save/restore context when getting colors for a different state
Getting colors for a state different from the current state of the
corresponding widget without saving the context might trigger an
invalidation and a redraw. Because this was happening from the draw
function this resulted in a redraw loop and constant high CPU usage.
This could be triggered by selecting text or searching.
