> When a GraphicsData object would exceed 8200 bytes in size, instead of moving
> the last area of GOCA data to a new GraphicsData and continuing from there,
> FOP currently moves the data into a new GraphicsData object, leaving the old
> one empty. This is technically not a violation of MODCA spec, but has caused
> crashes in AFP viewer software. My patch prevents GAD fields ever exceedining
> 8200 bytes and prevents GOCA instructions being cut up between segments.
> Below is an example of the current behaviour as of FOP 2.8 visualized with
> AFPExplorer and my fixed version with the same input data.
