generated dynamically which will stay static in the future. This applies
mainly to the search result favicon in front of search hits. These icons
will now be generated once, but then caches in the browser. There is
also a YaCy-internal cache for these icons which had prevented the
re-generation of the icons in YaCy, but this cache is now superfluous
since the browser should not call the servlet ViewImage again.
caused by a JRE bug, the PixelGrabber had to be circumvented using an
own frame buffer which can be read without a PixelGrabber. This resulted
in ultra-fast and much less memory-consuming transformation. YaCy images
are now generated really fast!
