Hi Ralf!

Nice to see you're contributing again back to Cacio!

This seems expensive.

One quick place where this can be done may be after blitting. or by
keepin track of your repaints and do after a repain operation (but you
should try to do a batch).

Depending on the application this may be good to do.

Another thing to do is to do every n painting operation or at each
refresh rate cycle.

I'll think some better places where you could do that and let you know.

Cheers,
Mario
