Hi,
GeoServer is just calling an iText Graphics2D object as if it was doing a
normal map paint,
there is no "vector" or "raster" mode, whatever happens inside that iText
object, happens,
GeoServer just tries hard to pass as many vector primitives as possible to
it.

Of course, if a fill is made of raster icons, it cannot magically become
vector, besides that,
it may be that some vector primitives get rasterized by iText, e.g., I see
a dashed line,
if you used "stroke-dasharray" GeoServer is calling a vector primitive on
the Graphics2D,
but it may be iText is building a raster representation of it.

Cheers
Andrea
