              Comment [ A very unique PDF that has a text layout that we haven't seen or no one has taken notices. When creating the bounding box we always he assume box should be create with the x,y at the lower left but in the instance of this pdf the font size is negative which creates right to left layout which is then mirrored by the current gs transform. The problem with the layout is that we create the bounding box incorrectly and everything goes sideways from there.

              I've added some code to detect the negative layout and thus we create the correct bound. Everything works as expected afterwards. ]
