st-scroll-view-fade: Include outer bound of pixel on border

Browse Source 
The fade shader will draw the fade effect up until the border pixel. If
we set the bottom right coordinate to the outer edge of the pixel we
might end up not drawing the fade effect on all of the pixels. This
could for example happen if one logical pixel (clutter stage pixel)
consists of more than one physical pixel.
