Thank you.
I setup a test page with a simple iframe with text 'inner frame text'.
And then I run in a debugger and set up a break point in
'DrawString'.
My question is from the stack track, I don't see nsSubDocumentFrame's
Paint() being called. And can you please tell me how does Gecko paint
the iframe?
Thank you.
