You can find the answer to this question at: 


which says:

Individual graphics elements are rendered as if each graphics element
represented its own group; thus, the effect is as if a temporary
separate canvas is created for each graphics element. The element is
first painted onto the temporary canvas (see Painting shapes and text
and Painting raster images below). Then any filter effects specified for
the graphics element are applied to create a modified temporary canvas.
The modified temporary canvas is then composited into the background,
taking into account any clipping, masking and object opacity settings on
the graphics element.
