Deprecated enum that previously controlled the minimum size and resize
increment of a FormFactorPart along each axis.
Deprecated. This item is deprecated as parts no longer contain a FormFactor to determine
their minimum size. The minimum size of all parts now behaves like "Custom" by
default.
Minimum size along a given axis is 1 * RateOfIncrease for that axis, except
in the case of the "Custom" FormFactor, which has a minimum size of 0.2 along
all axes.
