<test title="Color Testing">
	<description>
		This test validates the convertion of Java 2D Colors
		into SVG fill, stroke and opacity attributes.
	</description>
	<description>
		The test validates that color constants (such as Color.red)
		are converted to their equivalent SVG constants. It also
		tests that opacity is translated properly by painting 
		half transparent shapes.
