Description

I've just stumbled over a serious performance hotspot in the GOCA part when rendering a DataMatrix barcode using Barcode4J. I haven't had time, yet, to investigate if other graphics also exhibit that. Here's some profiling data:

org.apache.fop.afp.goca.AbstractGraphicsDrawingOrderContainer.getDataLength()
Time: 277'609ms (51%)
Own Time: 100'437ms (18%)
Invocation Count: 178'560

GraphicsBox.getDataLength() also seems to be involved here.

Just noting this mostly for myself (to revisit later).
