Predator has provided 5 possible suspects

1. Allow out of bounds coordinates in glBlitFramebuffer by sugoi@google.com
2. Rename signed normalized formats. by capn@google.com
3. Separate image depth and samples count. by capn@google.com
4. Allow blitting with out of bounds source coordinates by sugoi@google.com
5. Fix blitting of quad layout data. by capn@google.com

Assigning to capn@ for further triage.
