AW: Checked on WIN32 where GDI+ is used. It is not true that there is a gap top
and left; the topmost and leftmost pixel row are partially covered (blended) as
with half transparent, pretty much what could be expected with AA and object
polygon fill. This can not be seen too well due to the dark line around the
page. I do not see what i can do here with AA except also creating the outlines
as hairline.
Same is true for the rectangle: the edges are painted, but blended.
I experimented with GDI+ and it is not graphically correct (additive). Painting
all content with offset (-0.5,-0.5) does not lead to the top and left row being
painted completely. Also areas directly neighboured do not exactly close the gap
between them.
I tried to paint every filled polygon plus it's outline, but this does also not
work; against expectation the thus painted filled area is sometimes bigger than
the hairline around it. Anyways this is not possible to use since it does not
work with transparent shapes.
OTOH it would not be good to force special parts of the visualisation to
non-AAed; it would add ne more exception to the renderers and also lead to
problems when we one day want to rotate pages or other objects where we would
use such exceptions.
Investigating further...
