Binary dump of SNES residuals

[mspieg]

Apologies if this is obvious,  but is there a clean way to dump out  
SNES residuals (and or updates) (inside a DMMG) as binary vectors for  
debugging.


I'm currently using

-snes_monitor_residual

which is lovely for visualizing the residuals but uses VecView with  
the default Viewer set to draw and it would be useful to have a  
command line option to change the viewer type to binary (if it  
doesn't already exist)

I can certainly use  SNESMonitorSet with a custom monitor that sets  
up a binary viewer for SNESMonitorResidual, but I'm being lazy.

Any and all help greatly appreciated.

cheers
marc
