WrappedPoint missing in several method of the API

[hilaire]

In the DrGeoCanvas Smaltalk API, the following method will benefit to wrap point as MathItem Point:

#abscissaOf:
#angle:to:to:
#distance:to:
#ordinateOf:

[hilaire (hilaire-fernandes)]

Argument to #abscissaOf: and #ordinateOf: messages can be a point item or a vector item.
Therefore if only coordinates is provided (i.e. 4@5), we can't deduce if the user want a point item or a vector item.
I propose we assume a point item is wished by default, thus if the user write:

sketch abscissaOf: 5@4

DrGeo will wrapped this 5@4 coordinate to a Point item.

#angle:to: can also use wrapped vectors
