Instead of taking just vertical/horizontal offsets, take a ClutterMargin to allow us set the fade offsets on each direction specifically. Also, handle negative values in margins, the fade effect will run in the negative space left by the scrollview padding instead. Another difference now is that areas outside the extents of the effect will be transparent, instead of the effect ending abruptly past the given extents. This will be used by the app grid, in order to selectively let see either of next/prev pages while navigating. While at it, fix code style issues in st_scroll_view_update_fade_effect(), and clean up unused variables from the GLSL code.
