Description

I have attached an FO file that has a background colour on a table column with 0% width. This is needed as the columns in the table are used to form a primitive bar chart. When dithered backgrounds are enabled, an illegal IOCA object is created with a 4C triplet as follows:

4C02FFFFFF0000

The AFP Painter should avoid creating IOCA objects for a background if the objects width is <= 0
