Is there some way to DCHECK that the right context is current here?

[dhollowa, 2011/11/16 19:59:18]

Not really, no.  The view doesn't expose accessors for its context, it is
implied by call order.  That is the view's drawing traversal sets the context up
but the only way to get at it is via the notion of "current" context.  Lots of
pushing/popping, but no direct access.

Doesn't gfx::Size() have a constructor that takes an NSSize (or at least a
CGSize)?

Done.
