<Notes>
Start with a small grid number (2x2 for example) and gradually increase it to ensure
that the proper size is achieved.
Earlier settings will be lost if a lesser grid number is chosen after a larger grid
number.
Adjust the outer cursors like the red ones shown below and then adjust the inner
cursors like the green ones shown below.
The inner cursor settings will be lost if you adjust the outer cursors after adjusting the
inner cursors.
It is easier to achieve homogeneous deformation by using a lesser grid number.
