[PATCH v2 0/1] MR2657: d3d9/tests: test table fog z vs rhw with shaders, depth bias, oDepth..

[Aleksey Komarov (＠q4a)]

General idea of this test is to show that a lot of factors influence the fog when transformed and untransformed vertex format was used:
- Directly changing z and w (which is not equal in the corners).
- Changing projection matrix that change z and w.
- Using different programmable/ff vs/ps shader.
- Using different depth bias.
- Chaging depth in pixel shader (oDepth) may or may not affect to colors depending on the vendor implementation.
- And various combinations of above.

This gives `succ` in all cases on this configs:
- Windows 10 with Radeon HD 8400 or Ivy Bridge GT1 (Intel HD Graphics).
- Windows 7 with Radeon HD 6450.
- Windows XP with GeForce Go 7300.
