Revert of Fix recursive computation of filter bounds for drop shadow, (patchset #1 of https://codereview.chromium.org/481273005/)

Reason for revert:
This CL is currently breaking the Win7 and Win8 bots on some of the new tests (in DM).

Original issue's description:
> Fix recursive computation of filter bounds for drop shadow,
> morphology, blur.
>
> Because we're computing "backwards" from a clip rect of destination
> pixels to be filled to the required source pixels, we should use tail
> recursion rather than head recursion in onFilterBounds().
>
> This actually only makes a difference for drop-shadow, where
> the computation is non-commutative. Blur and morphology commute, but I
> moved them to tail recursion anyway for clarity (so all onFilterBounds
> use tail recursion).
