Subject: [PATCH] d3d9: Some Windows drivers do not like reversed fog.

The fog test used start = 0.9 and end = 0.1. This is perfectly ok in
theory, but some Windows drivers do not like it. Since this test tests
how fog is calculated with Vertex and Pixel shaders put the fog range in
the normal order(start = 0.1, end = 0.9), this fixes a number of fog
failures on ATI cards on Windows.
