[1/2] wined3d: Use texture2D to sample in pshader_glsl_texdp3tex()

[H. Verbeet]

Direct3D (pre d3d10 anyway) doesn't have real 1D textures. When MSDN
talks about doing a "1D texture lookup" it's really talking about
sampling from a texture with 1 as height, or at least one that doesn't
change in the y direction. What it comes down to is that we sample
from a 2D texture, but hardcode the y coordinate.

Changelog:
  - Use texture2D to sample in pshader_glsl_texdp3tex()
