The end of clipToImageBuffer is not necessarily reached with the next restore.
You can use combinations of save and restore between clipToImageBuffer and it's
corresponding restore. SVG Masking uses different save/restores between
clipToImageBuffer and the real restore.

At the moment we use clipToImageBuffer on three points. Filling/stroking texts
with gradients or patterns on Canvas, clipping text on a background for CSS and
SVG Masking. There is no implementation for SVG Masking on Skia, but there is a
patch for making SVG Masking platform aware at
https://bugs.webkit.org/show_bug.cgi?id=19243

And I don't know if it is possible to use clipToImageBuffer during a
clipToImageBuffer. So it's maybe necessary to store more clipImages:

context->save();
context->clipToImageBuffer();

...
context->save();
context->clipToImageBuffer();
...
context->restore();
...

context->restore();
