------- Additional Comments from Nikolas Zimmermann <zimmermann at kde.org>
A quick grep shows following users of m_clip:

PlatformContextSkia.cpp:   
canvas()->getTotalMatrix().mapRect(&m_state->m_clip);
PlatformContextSkia.cpp:	applyClipFromImage(m_state->m_clip,
m_state->m_imageBufferClip);
which are relevant.
The first place, sets m_clip, but the restore() call actually reads from
m_clip, if m_imageBufferClip is non null.
Is it possible to create a layout test triggering this? Anyhow, still r=me,
this is straight-forward. But if it had a test, it would be superb.
