wined3d: Add the bulk of the GLSL string generation functions. - Add a new file glsl_shader.c which contains almost every GLSL specific function we'll need - Move print_glsl_info() into glsl_shader.c - Move the shader_reg_maps struct info into the private header, and make it part of SHADER_OPCODE_ARG. - Create a new shared ps/vs register map for float constants (future patch will make ARB programs use this, too)

wined3d: Add preliminary support for constant boolean and integer registers in GLSL. - Separate the declaration phase of the shader string generator into the arb and glsl specific files. - Add declarations and recognition for application-sent constant integers and booleans (locally defined ones will follow). - Standardize capitilization of pixel/vertex specific variable names.

shader_addline(buffer, "T%lu = texture2D(Psampler%lu, tmp0.st);\n", reg, reg);
wined3d: Add the bulk of the GLSL string generation functions. - Add a new file glsl_shader.c which contains almost every GLSL specific function we'll need - Move print_glsl_info() into glsl_shader.c - Move the shader_reg_maps struct info into the private header, and make it part of SHADER_OPCODE_ARG. - Create a new shared ps/vs register map for float constants (future patch will make ARB programs use this, too)

wined3d: Add support for shader model 3.0 I/O registers. SM 3.0 can pack multiple "semantics" into 12 generic input/output registers. To support that, define temporaries called IN and OUT, and use those as the output registers. At the end of the vshader, unpack the OUT temps into the proper GL variables. At the beginning of the pshader, pack the GL variables back into 12 IN registers.
