Fixed defines for shadergen. Defines were "defining" structure properties out for IN structures.

example:

         // struct VertexData
         // {
         //    vec3 position;
         //    vec3 normal;
         //    vec3 T;
         //    vec3 B;
         //    vec2 texCoord;
         //    vec2 texCoord2;
         // } IN;
         //
         // varying vec4 _TEXCOORD2_;
         //
         // #define texCoord2 OUT_texCoord2
         // #define OUT_outVpos _TEXCOORD2_
