Light themes updated with hover-over states (Ubuntu 12.10)

Days ago, the new refreshed light themes landed in Quantal Quetzal, introducing a fancy yet "precise" built-in design, featuring rounded search areas, new checkbuttons and radio buttons, visually enhanced buttons, etc, basically, adding an overall qualitative + to Ubuntu 12.10's Ambiance and Radiance.

It seems that is now a common approach for Ubuntu developers, along with the work on key areas, to adjust, improve, enhance minor almost imperceptible visual items, thus generating a wave of consistency and "finished" desktop.

Light themes 0.1.91 have landed in Ubuntu 12.10, enriching its newly (days ago) refreshed look&feel via minor yet relevant bits.

The checkbuttons gained a hover over state, meaning, hovering the mouse pointer over a checkbutton presents the checkbutton with a subtle dark-ish shadow, subtle yet "enough" to transmit the user its clickable availability.

A definitely interesting part is how the "focused" state have been implemented, basically, moving the mouse pointer over a checkbutton "highlights" it by adding "shadows" to it, process perceived by the eye as a IN-&-OUT movement, 3D-no3D, expressing a fancy "out-of-the-ground" movement by moving the button's top visual "strength" to its bottom.

The same visual enhancements has been pushed into radio buttons, thus extending the new hover state on numerous applications.
