I did what Dirk and Dean suggested.

-- I return early from RenderSVGResourceFilter::buildPrimitives() if the number of children is greater than 10000 nodes.  There is no point in creating such FilterEffect in this case.  Checking the number of children nodes rather than checking the height of the FilterEffect tree saves us from doing two things. (1) traversing the FilterEffect tree till some maximum depth. (2) avoiding building a tree which is most likely to have no use at the end.

-- The test file was changed to be dynamically include many FilterEffect filters in the SVG.
