increment property
Adds the given value to the property's current value.
This must be an integer or a double value. If the property is not an integer or double, or if the property does not yet exist, the transformation will set the property to the given value. If either of the given value or the current property value are doubles, both values will be interpreted as doubles. Double arithmetic and representation of double values follows IEEE 754 semantics. If there is positive/negative integer overflow, the property is resolved to the largest magnitude positive/negative integer.
