you don't need to specify `elevation_value`. This parameter defines
constant plane surfaces (with fixed height). You need to specify other
surface-related parameters with given number of options. Eg.

m.nviz.image elevation_map=elevation,roadsmajor out=elev
mode=fine,fine resolution_fine=6,6 resolution_coarse=9,9
style=surface,surface shading=gouraud,gouraud
wire_color=136:136:136,136:136:136

This behaviour should be changed. If you do not define multiple values
for given parameters (like `wire_color`) then the module should use
default (single) value for all loaded surfaces.
