Rotates the point by the angle "theta".
This rotates the position of the point around the origin in the trigonometric standard manner; zero degrees is at the right, increasing degree angles are counterclockwise from the x axis to the y to the -x to the -y ....

| void geometric::point< contents >::pack | ( | byte_array & | packed_form | ) | const [virtual] |
Creates a packed form of the packable object in "packed_form".
This must append to the data in "packed_form" rather than clearing prior contents.
Implements packable.

References basis::attach().
| bool geometric::point< contents >::unpack | ( | byte_array & | packed_form | ) | [virtual] |
Restores the packable from the "packed_form".
This object becomes the unpacked form, and therefore must lose any of its prior contents that depend on the data in "packed_form". This is up to the derived unpack function to figure out. The "packed_form" is modified by extracting all of the pieces that are used for this object; the remainder stays in "packed_form". true is returned if the unpacking was successful.
Implements packable.
