ZPT macros work as if the macro markup was pasted into the template
that's using it. It's not like a function call that has its own scope.
That said, you can either use Kevin's suggestion and get to it via
context/@@view_exposing_the_macro/static (basically, the macro would be
looking itself up as a view), or the macro can refer to its resource
directory explicitly by package name: tal:define="macro_static
