[Bioperl-l] Need help updating Bio::Graphics regression tests

[Lincoln Stein]

Hi,

I've made a couple of fixes to Bio::Graphics in the 1.2 live branch that 
invalidate regression tests 1-3 and need your help creating replacement 
regression test files.  The issue is that Bio::Graphics uses GD, and GD 
produces very slightly different images (using different colortables) 
depending on the version of libgd and libpng that is installed on the system.  
I have created regression tests for some of the common combinations, but not 
for them all.

If you have GD running, please run the following command:

	perl t/BioGraphics.t --write

This will create the following files in t/data/biographics:

	t1.png
	t2.png
	t3.png

Please run the md5sum command on them, and check their signatures against this 
list:

	90cb99eb8cf8c401990e1bf768b9fe2c  t3.png
	263660adeb5bcad278ae2751ac2ca56a t3.png

If any of the files has a different signature than the regression test files 
listed above, please send me a copy of it so that I can include it among the 
test files.  Also, if you have a really old version of GD, the command will 
generate GIF files like t1.gif.  I don't have an old copy installed, and 
would be most obliged if you could send me the GIF versions.

Thanks,

Lincoln
