Still more changes... 
-Now it accesses the form bits array instead of the x and y
coordinates. This is a slight speed improvement:-). But it's on the cost
of the wave and fuzzy filters, I have not implemented them to the 
new model. Transparency is not preserved either...
-Adding new filters should be easier :-)

Any hints to improve appreciated.

Have fun.
