scroggo@google.com b340cf7e3d Only skip pipe playback for blurs GM in FIXED mode.
Only skip it when it would actually fail. Also add a comment
describing why it fails:

// SkCanvas::drawCircle, used by this test, performs a quick reject.
// The large size given to the device used by SkGPipeCanvas means that
// the device clip will not be set properly and circles will be
// rejected when in FIXED.
