restore css3pie if needed
during the implemetation of the derivation tree view for #7599 and #6866 it was necessary to upgrade
compass intermediately. After downgrading to 0.12.7 the compilation of the sass files currently fails with
ArgumentError on line ["58"] of /var/lib/gems/2.7.0/gems/fssm-0.2.10/lib/fssm/support.rb: comparison of String with 0 failed Run with --trace to see the full backtrace
, so I need to continue using a newer compass version.
This version is no longer compatible with the css3pie that was supported by compass 0.12.7
- decide if css3pie still is needed, that is if we still need to support older IE browsers (like IE 6 to IE 8 ??)
- upgrade css3pie in the zen theme or upgrade the whole base theme to a newer version.
