Fluid: Enable new flood-fill helper function
The flood-fill helper serves as a sanity check for scenes with complex
obstacles. Similarly to the holes filler function it ensures that there are no
holes in obstacles.
In addition, it ensures that there will be no holes resulting from multiple
intersecting obstacles.
In general, this commit should improve stability.
