------------------------------------------------------------------
I took a look at the PDFBOX-1870 file. The final image is really made of six
triangles, and then a hexagone shape is drawn in the middle. The line of the
hexagone is white, and its surface is black. So it is the white line that is
too small.
Both the pre-regression version and the current version have an identity CTM.
-The difference between the two versions is that the java graphics has an scale
of 1, while the current one has a scale of 4.16 (the number for 300dpi).- true
but irrelevant, solution coming up
