Have a bit of a conundrum here.
Many of our sites were setup with the mysource_files referencing within the Stylesheets (CSS) whereby images are being called via Squiz Matrix parsing http://manuals.matrix.squizsuite.net/designs/chapters/css-design-file
This is definitely a convenient way of doing it as using ./?a method is problematic and using the absolute data URL is less convenient. The problem lies when you want to combine and minify the CSS files via the CSS File Folder. Squiz Matrix refuses to parse the files unless they are in the same relative directory (I assume). In this particular site I am working on, the associated images are children of the CSS Design File and I can't clone them to become children of the CSS Design File.
My question - is it possible to still use the mysource_files referencing within CSS File Folder asset, if the referenced images are children of the CSS File Folder asset? Or would it be best to 'ditch' mysource_files referencing and just reference the URL of the absolute path?
