[FROM THE RED BOOK]

FILL 
....
Before painting, FILL implicity closes any open subpaths of the current
path. Tha insede of the current path is determined by the normal
non-zero
winding number rule (See section 4.5, "Painting")

FILL implicitly performs a newpath after it has finished filling the
current
path. TO preserve the current path accros a fill operation, use the
sequence

gsave fill restore

==================

EOFILL

Paints the inside of the current path with the current color, using the
even
othh rule ( see section 4.5) to determine what points are inside. Except
for the
choice of this reul, the behaivor of EOFILL is identicall for that of
FILL.

===================

CLIP

clip treats an open subpath of the curren path as of it was closed.
......
unlike FILL and stroke, CLIP does not implicitly perform a newpath after
it has 
finished using the current path.

========================

EOCLIP

behavior is like CLIP except for the even odd rule. DUDE !
