           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2

We can misuse PrintContext in several ways. We can call PrintContext::begin()
twice, we can call PrintContext::end() without PrintContext::begin(), and we
can forget PrintContext::end() after PrintContext::begin(). Bug 36049 is an
example of such mistakes.

Let's add a boolean flag to prevent such misuses.
