Speculative fix for recording texture-backed SkImages into SkPictures.

Speculative fix for recording texture-backed SkImages into SkPictures.

SkImages that are backed by textures are being recorded into SkPictures that are rendered in multiple threads. This causes multiple threads to access the same Gr- and GL context, neither of which are thread safe.

This change was suggested by junov@chromium.org as a possible fix.
