This reverts commit 7712db9c24.
Reason for revert: blink unittests and maybe vulkan+skiarenderer masks appear broken. The blink unittests had actually failed with original CL, but was missed because of focus on Android. Not sure what's going on yet.
Original change's description:
> Reland "Draw image filters directly under non-axis-aligned transforms"
>
> This reverts commit 6cafdc069b.
>
> Reason for revert: Fixes unit test failure in Android
>
> In the original version, this internalSaveLayer() returned early if the
> strategy was kNoLayer. This diverged from the old code that updated the
> canvas' clip bounds and then returned before making the layer. A comment
> had suggested this was maybe okay to switch to this early out, but it
> turns out that's not the case.
>
> In Android's unit tests, it queries the clip bounds on a recording canvas
> which always uses a no-layer strategy. However, we do need to set the
> clip bounds of these types of canvas' (or virtual wrappers of a real
> canvas) so that they stay consistent with a real canvas.
>
> The unit tests had two failures, first the bounds and second a color
> mismatch after reading back. However, the bounds test was an ASSERT_EQ
> inside an SkDrawable function. ASSERT_EQ aborts the current function, so
> it never ran the drawRect that sets the color to green. The later
> readback is outside the drawable function, so that test still happened
> and failed. The only real issue to fix is the clip bounds tracking; once
> that unit test succeeds, the color readback will work properly.
