[kepler-dev] Changing icons for composite actors

Hi Chad,

I may have not described my question fully. I know how to define icons for 
Kepler actors that either have lsids (saved in kar) or are java 
classes. The composite actors in the CPES workflows are neither "actors 
saved in kar" nor classes. They are simply ad-hoc subworkflows. That is, 
they have no lsids either.

For example, in the workflow there are unique (not too complex) composites 
to hide some specific, control related operations. They have the default 
green box representation of the TypedCompositeActor. I would like to 
show them as control actors (there is such an existing icon).

However, if this requires to save them as kars and 
define/register/cvs-commit them, I may quickly decide it is not worth to 
do it.

I can see in the Tree view of the workflow, that each component has an 
_svgIcon and _iconDescription parameters, obviously created and filled by 
Kepler when loading the moml file. Is there any way to influence this 
process to insert that icon name what I want, not the one which is 
assigned to TypedCompositeActor? Through a special _... parameter inserted 
by hand in the moml for example :-) ?
