Unify the way the different state's of a cache are shown in the timeline: * Baked: fully opaque * Cached: slightly transparent * Invalid cache: slightly transparent, dark diagonal stripes This improves accessibility since patterns are easier to recognize for colorblind or otherwise visually impaired people. The slight transparency is done with an alpha of 0.7 and the diagonal stripes use the cache's color at 50% value. Implements #108196.
