Adding a title offsets image column

[christophermclement]

When a fig.suptitle or ax.set_title is used it throws off the vertical alignment of an image column. When both are used the effect is ~doubled. The bottom column is ~correctly aligned but as one goes up the rows the misalignment becomes more severe.

Spitballing, it looks like the vertical alignment is set assuming no title and thus spaced according to where the rows would be if there were no title, but since the title offsets and compresses the table the images become misaligned. By the bottom row the effect is small anough to not be noticeable.
