[Bioperl-l] tests

[Lincoln Stein]

Hi Heikki,

Option 1:

Run BioGraphics.t with the --write switch:

	perl t/BioGraphics.t --write

This will create a set of pngs in t/data/biographics named 
t1.png, t2.png and t3.png.  Look at them visually and 
confirm that they are similar to the variants located in 
t/data/biographics/version*.  If so, move the new versions 
into the appropriate version directory.

Option 2:

I will disable the PNG tests completely.  Every different 
combination of libpng and libgd generates files that are 
visually identical but incompatible at the binary level.  
These tests aren't scaling.

The SVG version of Bio::Graphics is almost finished, and 
when done I will replace the PNG tests with SVG tests.  
Since SVG is a text-only XML format, it won't suffer these 
problems.
