Message:

Merge from lp:~petr-koupy/helenos/gui-optim.

The main improvements are:

• significantly faster rendering (making qemu/non-KVM usable) if user limits himself just to window movement and resizing (i.e. avoiding rotation, scaling and transparency)

• preview of the result of window transformation is depicted by a "ghost" frame following the mouse pointer

• changing of window focus feels more natural and intuitive (mouse click handler behaves more like in mainstream operating systems, window titles changes color to reflect whether they have focus or not)
