are selections part of kispaintdevice or aren't they?

e) make KisFilter::process const, but that involves changing the way the 
progress is reported
f) check that the configuration widget work, especially for filters using a 
custom KisFilterConfiguration, we have the option to keep the custom 
KisFilterConfiguration and then we need to add a 
KisFilterConfigurationFactory or to remove that custom KisFilterConfiguration 
(not all of them are needed).
