Try to avoid blackboxes

Unbelievable: Just this one square where I uploaded the screenshots yesterday
uses 352 inline images and 352 rectangles to draw black and white lines in
turns. I tried to avoid the drawing of the black lines (eofill with
rectangles), but it changes too much in our PDF suite. Therefore I use now our
new switch thinLineMode: If it is NOT thinLineDefault AND it is eofill AND it
is just a line with pixel size less than one, the line is NOT painted.

@Albert: You can see the effects in okular if You use the "Enhance thin lines"
option. BUT from zoom factor > 110 up to zoom factor < 250 You still get black
boxes. Below 110 the boxes are white and the text inside is readable, from 250
on the blackboxes begin to disappear  and from 350 % the text is readable
again. I'm passionless if You accept this patch or throw it away.
