They are somewhat independent (you can use the new layout with the old style
and vice versa) but they belong together.
Tested in Firefox, Safari, IE5.5, IE6, but there are still some features
to be implemented before this is ready for 'main'.
To use, first add "new_style_june_2007=true" to the app:universe section of
universe_wsgi.ini (this gives you the new layout). Second change document_root
to "%(here)s/static/june_2007_style/blue" in the app:static_style section.
Style Features: simplifications, fewer 'hatched' images, space savings in some
places, small changes to the color scheme (same general feel, but the colors
are better matched). Main changes are to history, the new style support nested
datasets much better.
Layout features: no framesets (just iframes, some of which can be replaced with divs and ajax down the road). Frames are resizable and hideable. Tools can provide width hints and history will automatically hide (try UCSC main to see this).
Also, the consolidation makes the total file size substantially smaller. In addition, there is a "scripts/packed" directory that contains highly compressed versions of the javascript files. This should be used for production deployment. The initial load size is reduced by ~80%, before considering gzip and caching.
