The header files in freestyle utilize the using-directive at the global file scope. This is a bad practice as it pollutes the global name space causing possible ambiguous reference compilation errors. In particular, the DNA files that are included by freestyle will cause those ambiguous reference errors when the developers adds a DNA member with a type name that also exist in the Freestyle name space, such as Curve and possibly others. This patch does the minimal work needed to resolve that by moving the using-directives from the headers into the corresponding translation units.
