This reverts commit 8636e13c2d.
Reason for revert: recording canvases with really big float bounds could
produce a non-empty integer rect bounds that became empty after mapping
it to (0,0,w,h) for the device. This meant resetForNextPictures logic of
updating QR bounds directly from the input bounds allowed state to become
inconsistent with computeDevClipBounds().
PS1->PS4 shows the 1-liner to just compute bounds from the device. This
means that, for now, we preserve the behavior of setting the QR bounds to
be actually empty. skbug.com/10997 is added to fix the underlying issue
with recorders and excessively large float bounds. If that change landed
first, I'd be able to reland this w/o any modifications, but have decided
that it's better to have all locations that modify fQuickRejectBounds use
the exact same expression.

This reverts commit 6c1191d749.
Reason for revert:
- the lowest-level issue is fixed in https://skia-review.googlesource.com/c/skia/+/337076
which prevents bad replaceClips from going beyond the device bounds
- but this also updates the original CL so that we don't call
replaceClip in these problematic situations. The old behavior of
effectively downgrading a saveLayer to a save when the new device
fails to allocate is better behavior.
- now the bounds tracking is still consolidated as before, but only
applied when the kNoLayer_Strategy is used, or the layer should be
empty (in which case replaceClip() is passed an empty rect and
everything works out).
- when the layer fails to allocate, we add a clipRegion to restrict
nested draw calls to what would have been the layers bounds, while
still respecting the old clip (that normally would have been applied
on the layer restore, but won't because there's no layer). This is
somewhat pedantic, and is probably a rare case in the wild, but it
makes some of our SkCanvas tests easier to deal with.
- This is because, if you just make an SkCanvas(width, height) directly
you get an SkNoPixelsDevice but also use the kFullLayer_Strategy.
SkNoPixelsDevice always fails to create a layer (since it's meant to
be used with subclasses of SkCanvas that return kNoLayer_Strategy,
like SkNoDrawCanvas).
- applying the failed layer bounds as a clip keeps the canvas' reported
bounds as accurate as possible in this case.
- in the future, it may be worth updating how SkCanvas can be
constructed to avoid this, and overhauling the unit tests but
I didn't want to further delay these changes.
- it's important that replaceClip() is still used for the kNoLayer case
because it allows image-filtered layers to expand the clip bounds
until the restore. This keeps any virtual canvas or recording canvas
completely in-sync with the base canvas or eventual real canvas that
is backed by a device that actually draws.

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.
