we need to find out a way to hide some filters from the ui because they are not implemented yet. These filters are feFlood, feTile, feImage and feComponentTransfer

feImage is only partially implemented.

I wrote the patch that is attached to this email. It seems to work, but it crashed once when I tried to add a primitive to an opened SVG that contained one of these four filter primitives.

Maybe we should instead let these 4 primitives listed on the combobox but display a message saying that they are part of the SVG specs but not implemented yet.
