Add a new assertion for isFill

[Deee92]

Hello,

I noticed with mutation testing that the behavior of org.apache.pdfbox.pdmodel.graphics.state.RenderingMode.isFill() is not specified.
If the body of isFill() is replaced with return true; or return false;, no test fails.

Here is a test case that specifies it with a new assertion.

@Test
public void testIsFill()
{
    // Arrange
    final RenderingMode objectUnderTest = RenderingMode.FILL;

    // Act
    final boolean retval = objectUnderTest.isFill();

    // Assert result
    Assert.assertEquals(true, retval);
}

What do you think?

Thanks!
