the search for graphics is kind of fuzzy and dates from the time that we 
were still using dvi (different backends)

- without suffix: try the best quality (depends on spec driver support)
- with suffix: try that first, else locate alternative
- same as parent file: try to avoid circular loading (keep in mind that tex 
code can be a graphic, i.e. buffers can be scaled)

- all these are combined with a search over several paths, utilityfile, etc

also, most of this is overloaded when using figure databases -)
