[PATCH] gdi32: XFORM matrix in PlgBlt() is calculated incorrectly

[Alexander Almaleh]

As suggested by Sebastian Lackner, I am submitting his much simpler version
of the fix. Only one line is touched. The patch file is attached.

The bugzilla link is http://bugs.winehq.org/show_bug.cgi?id=36504

I see that the file was scrubbed, I don't know why, so I'm pasting it, just
in case.
