If you do that, you should use gl_FragData[] for *all* render targets,
including the first one. gl_FragColor will write to all render
targets.

wined3d: More shader fixes / new instructions

[Jason Green]

Makes sense.  Please use this patch instead.  Everything is the same:

- Replace gl_FragColor with gl_FragData[0] for GLSL pixel shader output.
- Subtract 1 more constant from total GLSL allowed float constants to
accommodate the PROJECTION matrix row that we reference.  Some of the
shaders in the Settlers 2 demo were failing due to accessing too many
constants.

(Settlers 2 still doesn't render correctly due to not supporting
multiple render targets, but that should be the last major roadblock
for it)
