Classes
class	SYMBOL_CLIPBOARD_FIXTURE

Functions
	BOOST_AUTO_TEST_CASE (SvgExport_ContainsPins)
	Test that a symbol with pins produces SVG output.

	BOOST_AUTO_TEST_CASE (SvgExport_ContainsRectangle)
	Test that a symbol with a rectangle produces SVG output.

	BOOST_AUTO_TEST_CASE (SvgExport_ContainsCircle)
	Test that a symbol with a circle produces SVG output.

	BOOST_AUTO_TEST_CASE (SvgExport_ContainsPolyline)
	Test that a symbol with a polyline produces SVG output.

	BOOST_AUTO_TEST_CASE (SvgExport_ContainsText)
	Test that a symbol with text produces SVG output.

	BOOST_AUTO_TEST_CASE (BoundingBox_Pins)
	Test that bounding box is calculated correctly for pins.
