the area of the smallest ST to be drawn is determined by (tol * S),
where S is the total area for plotting. No restriction is applied to `iter`

.

If the original triangle is an obtuse triangle,
the largest value of `iter`

is 12.

tol: A stopping creiteria to draw the sub-SPT. Default value 0.0001.

##### Value

The dimension of the ST will be returned if the original triangle is an acute triangle.
