Hi,
i noticed that sometimes pixbufs producers stop caching converted images
and do conversion on each get_image call. i found that it happens
because of cached pixbuf, image and alpha been dropped from cache
because of cache limit.
attached patch implement extending limit of that cache.
it similar to:
