    Attachment: PDFBOX-1094-094730.pdf

Page 3 of the attached file PDFBOX-1094-094730.pdf has this exception:
{code}
java.lang.IllegalArgumentException: Width (0) and height (0) must be > 0

{code}
The reason is that the file has negative XStep and YStep values (which is not illegal), and has floating point values (which is not illegal either, see previous commit). Somehow there's an empty rectangle created in getTransformedRect(), at.createTransformedShape(rect).getBounds2D() does not work properly, my next commit will fix that by using a different method to transform the rectangle.
