scPrintTwipsMsgs: Use top-left of output-area as the refpoint

We can't use the transformed version of editeng origin, since it need
not be in client view area depending on text alignment, which is
unusable as far as the clients are concerned.  Top-left corner of
output-area is always guaranteed to be in client view area independent
of text-alignment settings.
