I have an [Omega][1] subtheme that I am working on, and a request has come in to have a zone and all regions within the zone not be gridded.  By not gridded, I mean that I need the zone and all regions inside it to not be bound by any of the widths that [960.gs][2] imposes.  Just having the full width wrapper around the zone is not sufficient for that the requested layout.

I am not sure what the best way to do this is.

Inside `template_process_zone()` I can remove the grid classes from `$variables["content_attributes_array"]["class"]`  and inside `template_process_region()` I can remove them from `$variables["classes_array"]`.  This is a little messy because it assumes prior knowledge of all the grid classes (or at least the patterns), but it mostly managable.

The problem is that I can't see how I can figure out what zone I am in from within a region.  I want to avoid hardcoding region names in the `template_process_region()` for those to degridify.

I could also override the grid with CSS for a particular zone, but there are a lot of rules to override to future proof any changes.

Is there a well tested solution to this or other options that I am not considering?
