You are correct, [NSImage imageNamed:] should according to the
specification only look in the main Bundle. So Gorm and later NIB
loading will face the same problem as GModel. When loading an image from
a NIB (gorm, gmodel) file from a different bundle, the image names will
be looked up in the main bundle. Your code is a nice workaround for the
GModel loading, but wont help in the other cases.

Does anybody have a nice and clean idea to work around this?
Should we have something like a current bundle, which gets set in the
NIB (Gmodel, Gorm) loading code and will be used, if resources wont be
found in the main bundle?
