The cache is not used if the colors change, right?
I have implemented a pulsing icon using alpha.
Is a poof of concept patch (does not remove the unused properties), but now
does not render the icon every time.
I profiled with cProfile using the Martin instructions, and I think the
graphic show a improvement,
but I didn't see a big reduction in the startup time in the activities. (I
didn't tested it in XO 1.0)
Patches and profile graphics can be downloaded from
