Bob Owen c3f67cea48 Bug 1156742 Part 1: Change Moz2D recording, so that it can be used in isolation. r=bas
These are mainly changes to make sure we have recorded relevant dependencies to each draw operation.
Where we can't record them on the fly like this, it makes sure the object has originated from our DrawTarget.
