I'm wanting to use the generated rrdgraph images as textures in an openGL 
application. And as such, opengl really prefers the textures to be a multiple 
of 2 in dimension... SOme opengl implementations seem to work OK with odd 
sizes, but some just prefer you to stick to the (Older) standards.

1.2.something, but the closest I can find is the -j flag which only does the 
graphed data... No legend, grids, titles etc...
