Echo lighting

[Charlie Brej <fedora-art brej org>]

What are the rules on the lighting on the blue areas of icons?

Does each blue area have its own radial gradient point like in:
http://git.fedoraproject.org/?p=hosted/echo-icon-theme;a=blob_plain;f=trunk/Echo/48x48/actions/media-seek-backward.png;hb=HEAD
or do all areas have the same point like in:
http://git.fedoraproject.org/?p=hosted/echo-icon-theme;a=blob_plain;f=trunk/Echo/48x48/actions/media-seek-forward.png;hb=HEAD

Should the lighing be present in the 24x24 versions? like in:
http://git.fedoraproject.org/?p=hosted/echo-icon-theme;a=blob_plain;f=trunk/Echo/24x24/actions/media-skip-backward.png;hb=HEAD
or not like in:
http://git.fedoraproject.org/?p=hosted/echo-icon-theme;a=blob_plain;f=trunk/Echo/24x24/actions/media-seek-backward.png;hb=HEAD

Either way, I will have a go at making the media ones all one or the other.
