Returns a constant pointer to the information at the index "field".
If no information is stored or the field is out range, then NIL is returned.

| drawable * picture::acquire | ( | int | index | ) |
Retrieves a "field" from the amorph, taking responsibility for it back.
This function is similar to get, except that the contents are pulled out of the amorph. The contents will no longer be destroyed when the amorph is destroyed. To store the modified contents again, use put, and then the amorph will take over management of the contents again. Note that the index is not zapped with this function; the acquired "field" will simply hold a null pointer.
