The high-level function creates a new lazy snapshot which is not what we
what - we want a snapshot now!

Thanks to subsurface recursion. There's a pattern here, but no clean
solution has yet presented itself.

Ouch, a nasty bug surfaces after rearranging code to fix the others.
Another self-copy loop this time through a subsurface of a recording
surface.

And not the backend directly as this bypasses the extra steps taken in
the higher level to do common actions such as detach snapshots.

This is the root cause of the issue why we never succeeded in
implementing deferred snapshot correctly; that is we decoupled the
source from the target in the upper layers before we make the coupling
inside the lowest level of recording surface. By deferring the copy, we
never saw the detach-snapshot in time.
Fortunately this was only an issue for backends that implemented strong
immutable source semantics! The oversight implies that we need to push
down a similar flush mechanism into all backends.
Fixes self-copy.

It was supposed to be the centre point of e849e7c92, but I had a little
battle with git and lost...

As handling joins/caps between line segments shorter than
half_line_width is tricky.
Rather than also fixing the bug in traps, remove that code. The plan is
to avoiding hitting the traps code, short-circuiting several steps along
the fast rectangular paths.
Fixes line-width-overlap.

Specifically don't transform SOURCE into a CLEAR as the paginated
backends may not be able to handle the new operator.

They are internal and used as such, but we still need to prevent them
from escaping into the public domain.

As we report the status back to the caller who then decides whether to
take appropriate action.

I forgot to proof-read the patch before pushing and forgot I had left in
some damage from trying to get skia to link using libtool.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
Still hopelessly broken. Requires compiling cairo to use static linking
and then still requires manual linkage to workaround libtool. Lots of
functionality is still absent - we need to either find analogues to some
Cairo operations or implement fallbacks - but it is sufficient to
investigate how Skia functions in direct comparison with Cairo for
tessellation/rasterisation.
Caveat emptor.

Broken (never set!) since the clipping overhaul. We could emulate the
xcb code to avoid setting it unnecessarily...
Fixes partial-clip-test.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
When painting with an unbound source, we would miss that the clip
extents were smaller than the mask extents and remove the solitary clip
(believing we were bound by a tight mask). For painting this is
obviously wrong, and due to a combination of bugs that set the mask to
the bound extents and then the failure to spot when that mask was larger
than the clip.

It is convenient if the user can simply enable the use of the commented
write-to-png operation just by removing the preceding '%'. However, to
do so we need to make sure that the line is stack-neutral and so need to
pop the surface that we place onto the stack after writing the png.
