Re: wined3d: Use higher precision to convert floats into text.

[Stefan Dösinger]

As Henri said in the bug report, we can just declare the LC* uniform instead 
of constant and load them once at program link time. This way we loose the 
ability to tell the compiler about the constants, but I doubt this changes 
anything, but we can simply pass a float * to opengl witohut having to 
convert to a text. For ARB shaders we can use the program-local environment 
and load it at compilation time.
