17641	Tweaks and optimizations for Twenty Eleven images	demetris	iandstewart	"See tweaked images in the linked ZIP file. The tweaks are:

 1. A light grey border added to the preview image of the default colour scheme (light.png) so that it works better against the white background of the default Dashboard theme.
 2. Lossless compression of all PNG images of 2011.
 3. Removal of metadata from the JPEG headers and from their thumbnails, which saves quite a few kilobytes.

I run the PNG images through optipng, advpng, and then optipng again, at extreme settings.

The JPEG images I simply dropped on to Trimage (a tool similar to, and inspired by, ImageOptim for OSX).

A further optimization for the JPEG headers would be to apply lossy compression, which will give us huge gains in size. I will open another ticket for that."	enhancement	closed	normal	3.2	Bundled Theme	3.2	normal	fixed	has-patch	demetris iandstewart
