Brad Werth 53312c5a92 Bug 1450208: Change nsRange::ExtractRectFromOffset to use simpler, hopefully safer logic to determine whether text is vertical. r=bz ...

Instead of checking nsIFrame::IsTextFrame() and then casting to nsTextFrame,
the new code just checks the writing mode of the frame. Less casts; less
chance of pointer errors.
