+    test1 and test2 test -moz-image-rect() where the image rect is specified by
+    mixed pixel values and percentage values.
+
+    -moz-image-rect() can also take a floating point value for each side, and
+    each floating point value (after percent to pixel conversion) is rounded to
+    the nearest integer.  test3 and test4 test if the rounding operation is
+    working as expected.
