clutter/actor: Round to 256ths when projecting for picking

Browse source 
Picking is specially sensitive for float precision, and tests can
easily fail when something changes, even if ever so slightly. A
simple way to workaround this is by adjusting the projected points
using the same procedure described at 67cc60cbda.

Round projected points for picking to 256ths.
