Title: mlab.savefig with positive magnification fix

I tracked down the source of a fairly old bug in mlab.savefig() to some tvtk code which directs the WindowToImageFilter to use the back buffer, causing snapshots with magnification>1 to produce erroneous output. I don't know why this design choice was made, but I ran the tvtk test suite and found no regressions.
