Override this function with the implementation of your filter.

This is a low level function that expects all the conditions for the

Parameters

device	be met. Use usual process() methods instead.
device	the paint device to filter
applyRect	the rectangle where the filter is applied
config	the parameters of the filter
progressUpdater	to pass on the progress the filter is making
