In kestrel (1.3) we now honour the settings made by an application
though the PageFormat to specify the positioning on the paper of the imageable
area. ie we properly adjust the PathGraphics implementation class's transform
so that it compensates for the printer margins.
So, for example specifying margins of one inch in page format results in precisely one inch margins all round.

The same has not been done for the bandGraphics used for raster printing.
the conseqence is that the printing maybe shifted down & to the right resulting
in larger than specified top & left margins and smaller bottom & right margins.

This is not a major problem since the raster path is no longer used in most
printing and in any case does not affect anything other than a slight offset
of the printed area.
Specifically only pages which set colors with an alpha component will
be affected.
