Chris Wilson	9b53bc7c65	Cache solid patterns ... We use a small cache of size 16 for patterns created from solid colors, e.g. cairo_set_source_rgb(). This helps with toolkits that draw many widgets using the same colour scheme. The cache uses a static index variable, which itself acts like a cache of size 1, remembering the most recently used colour. So repeated lookups for the same colour hit immediately. If that fails, the cache is searched linearly, and if that fails too, a new pattern is created and a random member of the cache is evicted.	2007-03-20 18:21:53 -04:00
