* That makes CMYK look a little less broken...
* Added supportsPainting and progressEnabled flags to the filter interface
* Use the tile size directly instead of via getters: callgrind showed that

* Make the autogradient box a little smaller
* Make the layer box a little smaller
* Actually fill the filters list with filters (but selecting them doesn't
  do anything yet)
