Fix file viewer position for tall SHR images 

The images in Paintworks PNT files are 2x the height of the SHR
screen.  The rich edit control was ending up scrolled to the bottom
of the image, which is bad because many of the image files don't
really have anything interesting in the bottom half.  This shifts
the position back to the top.

Also, some minor source code touch-ups.
