This test verifies that the 'elevation' attribute is interpreted as a complementary value to the z-axis in degrees.

The test shows four different elevation angles that can be used for feDistantLight source. The four different feDistantLight light sources are used in three different filter cases; feDiffuseLight, feSpecularLight and feMerge which merges both feDiffuseLight and feSpecularLight to form a single filter. Using four different elevation values in three different filter cases gives twelve different filters. All twelve filter cases are applied to a vector graphic and then to a raster graphic. The vector graphic results are shown to the left and the raster graphic results are shown to the right.

Run the test. No interaction required.

The test has passed if

The top row has from left to right for a single graphic set:
- A green square with a black circle inside of it
- A black square
- A black square with a green semicircle inside the lefthand side of the rect
- A black square with a green semicircle inside the righthand side of the rect
The middle row has from left to right for a single graphic set:
- A green square with a white circle inside of it
- A green semicircle pointing to the right on top of a white background
- A green square with a white crest inside pointing to the right
- A green square with a white crest inside pointing to the left
The bottom row has from left to right for a single graphic set:
- A green square with a black circle inside of it
- A black square with a green semicircle inside pointing to the right
- A green square with a circle inside that has a shadow on the righthand side and a reflection on the lefthand side
- A green square with a circle inside that has a shadow on the lefthand side and a reflection on the righthand side

If the test shows any red, the test has failed.
