huge-region.html uses a blur filter in a huge element which previously wouldn't be filtered at all.

This test was timing out in an early version of this patch, which triggered the adjustment in the maximum kernel size (from 1000 to 500). In my machine (OSX 10.8.5, i7 at 2.4Ghz) both css3/filters and svg/filters are running fine, I tested it before sending the patch.

I see that there are the following issues:

a) The blur effect is a tad slower than it should be (but, I started looking on this by smfr suggestion #120813).

b) huge-region should really become 2 tests: one for invalid blur values (it uses 2147483648px which will be clamped to 500). And another for big regions.


How you gentlemen feel would be the best way to handle this?
