wine/dlls/wined3d/shader_sm1.c
Henri Verbeet e5719e9899 wined3d: Use a wined3d_string_buffer to dump the intermediate shader code. 
Instead of abusing TRACE. There's probably still some room for improvement.
There may also be value in dumping things in a format that's compatible with
D3D shader assembly, but I don't think it's a priority.
