size
Maximum width and height of drawing, in inches
If only a single number is given, this is used for both the width and the height.
If defined and the drawing is larger than the given size, the drawing is uniformly scaled down so that it fits within the given size.
If size ends in an exclamation point "!", then size is taken to be the
desired minimum size. In this case, if both dimensions of the drawing are
less than size, the drawing is scaled up uniformly until at least one
dimension equals its dimension in size.
There is some interaction between the size and ratio
attributes.
