You are right. To get back to solid fill you only need to set the pattern
ptr to NULL. This is more efficient then using a pattern of all F's.

The graphicss library ignores the size unless the the ptr != NULL
so it does not matter what the size is when going to a solid fill
 as a matter of fact a size of '0' is legal and indicates an
areafill pattern of height 1.
