Bug 970348 - Add background-blend-mode reftests corresponding to the csswg test plan. r=roc, r=heycam * 5.3.1: Blending between the background layers and the background color for an element with background-blend-mode. Most of section 5.3.1 is covered by other tests. Add the missing tests of the 5.3.1 section of the test plan. - Test 9: SVG image and background color (SVG as data:uri) - Test 10: Animated gif image and background color - Test 12: background-blend-mode on element with 3D transform * 5.3.2: Background layers do not blend with content outside the background (or behind the element). - Implementation of tests 2 and 3. Test 1 is already covered by background-blending-isolation.html. * 5.3.6: background-blend-mode for an element with background-position * 5.3.7: background-blend-mode for an element with background-size * 5.3.8: background-blend-mode for an element with background-repeat * 5.3.9: background-blend-mode for an element with background-clip * 5.3.10: background-blend-mode for an element with background-origin * 5.3.11: background-blend-mode for an element with background-attachement * Add extra tests for the background-blend-mode CSS property: Add some invalid values to the background-blend-mode property definition so that it can benefit from existing invalid property tests.

<!-- Blend two background images having background-attachment: fixed and scroll respectively  -->
