Details

In the process of converting from twips to pixel's we are sometimes off by one
pixel because of roundoff error. This results in calls to invalidate the frame's
rect which are sometimes 1 pixel too narrow. It may make sense to condition the
location of a frame so it's twip coordinates coorespond to pixel boundary.
The problem is the x,y coorindate may contain a twip value that is a fraction of
a pixel. When the width of the frame is added to the x coordinate the number of
pixels will vary depending on the x corrdinate's sub-pixel twip coordinate.
Double submit.
