The easiest workaround I could figure was to add a parameter to the
Agg2D object constructor. That should, in theory, allow the use of any
pixel format available in AggPas.
The ptcpas/ptcgraph units I used are the ones that came with fpc 3.0.1,
there was no need to download anything. They worked fine, except for one
48 bytes memory leak reported by heaptrc and that I left unfixed.

Also, for the example
to work, the agg object constructor must be modified as well, I included
all the info in the example header.
I noted the remarks on the image buffer format being hard-coded for the
Agg_2D unit. I'll make a plan for improving that, using some Factory
(design) Pattern to register the pixel buffer format of interest.
I think the example program
(aggpas_ptcgraph_output.pas) fits well together with the other demos in
fpGUI and PtcPas/ptcgraph packages, so adding it to the packages would
help, regardless whether graph.PutImage documentation is updated.
Thanks. I'll download the ptcgraph unit and give it a test. I'll all the
demo to fpGUI's AggPas demos too. It will be a good addition.
