Don't process filters if the input region is exceptionally large. https://bugs.webkit.org/show_bug.cgi?id=83317 Reviewed by Simon Fraser. Source/WebCore: An extremely large element causes problems with filters, either by taking too long to compute the output or using too much memory. The filter engine already has some constants for maximum expected size. Make sure the render tree checks them before deciding to apply effects.

This element is too big to filter.
