mapnik/test/unit/svg/svg_parser_test.cpp
Mickey Rose 05b66fc355 refactor svg_parser_test 
- moved some boilerplate to helper struct test_parser
- added REQUIRE(!parse...) to parsing error tests
- changed parsing error tests to compare full error lists instead of
  just count and then individual messages (if count was different, you
  were left in the dark with no messages at all)
- changed some double-quotes in errors to single-quotes
  (corresponding change to parser follows)
