    calculate the dimension of the effect previews automatically
    
    this is done by getting the viewport dimension, subtracting
    the borders and then dividing by three. if there are less than
    9 effects on the last effects pane, we want to still start
    putting the previews in the upper left corner. in fullscreen
    we simply use the same size.
