GMOD/jbrowse — Issue #69: Customizable track glyphs

## Current State ##

The current implementation (as of b5d2a65..., 24 Sept. 2009) provides few methods for customizing the feature glyphs within a single track. These
’customizations’ are defined by the strand/phase state of the feature, and
allow only for a limited number and type of glyph selections. This differs
substantially from the Gbrowse glyph generation scheme, which permits broad
glyph customization through perl callbacks in the configuration file.

## Concept ##

It would be useful for users to be provided with some means for controlling the
glyphs selected for individual features within a track. There are (at least)
two immediate benefits to this.
* It will be easier to ’combine’ multiple data types into a single track
while maintaining the visual distinctness of each data type.
* It will provide for (possibly) more informative ’dynamic’ glyphs.
