gtkrc using 2 engines

["Riswick, J.G.A. van" <J G A v Riswick tue nl>]

HI!

In the gtkrc file one can define something like


style "defaultenginestyle"
{
  fg[NORMAL]  ="#ffffffffffff"
  bg[NORMAL]  ="#9900991b99fe"
  engine "defaultengine"
  {
  }
}

widget "*" style "defaultenginestyle"



then all widgets are drawn with the 'defaultengine' 
engine. Now I was wondering if it is possible to add 
a second section like this, with  'anotherengine',
and a statement like:


widget "another-widget-name" style "anotherenginestyle"


so that widgets with this name get drawn by the other 
engine. Is this possible? (Maybe this is pusing the 
limits a bit. What I'd like to do, is for normal 
applications to use thin lines (1 pixel) and some
special applications to use 2 pixel lines in drawing buttons
etc.)  I tried it, but it didn't work.
But then, I also tried to define a different widget style
using *the same* engine, and different colors, but that 
also didn't work, so I'm doing something wrong. Maybe
someone has a good idea..


best regards
