Hi Andy,

The Ensembl DAS renderers don't use the Bio::Graphics package, and so 
custom glyphs from Gbrowse will not necessarily be available in Ensembl 
(of course, the converse is also true).  The only set of glyphs that 
are specified are, as you say, listed in the DAS documentation, but 
you'll probably find implementation differences between DAS clients 
here too: the stylesheet spec is rather open to interpretation.  Then 
again, it's only supposed to provide "hints to clients on how the 
annotations should be rendered visually".

On the upside, new glyphs are pretty straightforward to implement in 
Ensembl, and I'd be happy to help if you have specific requirements.  
The Ensembl web guys would undoubtedly be happy to add new glyphs into 
the distribution if they are generally useful.

Regards,

Jim
