skia2/debugger/QT/SkDebuggerGUI.cpp
scroggo@google.com 12705329d0 Allow creating a picture from skp to fail. 
Replace the current constructor for creating an
SkPicturePlayback to a factory. In the factory,
check for incorrect data that would result in an invalid
playback. If the playback is invalid, return NULL, and
return NULL from SkPicture's factory as well.

Update SkTimedPicture(Playback) as well.
