Did you create a generic converter, or did you just hard-code the results you got from manually rotating the page? I'm sure it's possible to abstract this transformation to a formula that could be applied to the quads to rotate them so that they fit the page's rotation. I just can't seem to figure it out... I actually think that the Matrix2D object in Acrobat's JavaScript does that, but it's too opaque for me to figure out how it works, exactly. I can post the source code for it, if anyone is interested.
