(sorry, I missed your last paragraph and question)
Ok, so application A is using cairo to output a PDF document, and
application B to display stuff on screen via GDI. Two apps using two
cairo API chunks which are optional to compile. Each app will break if
the wrong cairo.dll is shipped with it, but I want both to work with
the same cairo.lua file, so I don't think the argument "your app will
break anyway" applies to middleware.
