[gradsusr] filling display with map

[Jeff Lake]

Its been a looong while since I have used GrADS to map, primarily use it 
to create shape files...
how on earth do you get the map to fill the image ??
Ie... I have this

'set gxout shade1'
'set mpdset mres'
'set grid off'
'set grads off'
'set mproj lambert'
'set clevs -15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0'
'd no4lftx180_0mb'
'run cbarc'
'printim rap4liftx_HHH_XXX.png png x1200 y900 black'


and it produces
