BackgroundImage does not work with many filters

Bug Description

Gaussian blur requires a larger area than just the area shown to render correctly. This mostly (if not always) works when blurring an object directly, but when using BackgroundImage too small an area is given to the blur filter. See the attached files, one uses BackgroundImage, the other use in combination with a mask, the first is rendered with discontinuities, the other is rendered just fine.

As someone remarked on the mailing list, the problem is not just with Gaussian blur. Apparently feTurbulence, feMorphology, and probably feConvolveMatrix also suffer from this bug.

It occurs also with Displacement Map and Offset.

This is probably related to or the same as bug #194928 (haven't verified that it is indeed the same issue yet though).
