Hello,

just to let you know, the lp:~petr-koupy/helenos/gui-optim branch is prepared
for merging into mainline. Among others, it resolves the following tickets:

http://trac.helenos.org/ticket/478
http://trac.helenos.org/ticket/482
http://trac.helenos.org/ticket/483
http://trac.helenos.org/ticket/484
http://trac.helenos.org/ticket/485

For those that are not familiar with the tickets, 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)

If you don't have any objections, I will eventually merge the branch into
mainline and close the tickets. Right now, I am however unable to properly test
the branch with recent mainline changes because of i8042 performance issue that
is currently being investigated by Jakub. Therefore, I will probably wait until
it is resolved. In case anybody is eager to have the GUI improvements rather
sooner than later, and is able to test it in VirtualBox or qemu/KVM without
the significantly lagging mouse pointer, feel free to merge it instead of me.

Petr
