glUniformSubroutines loads all active subroutine uniforms for shader stage shadertype of the current
       program with subroutine indices from indices, storing indices[i] into the uniform at location i.  count
       must be equal to the value of GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the program currently in use at
       shader stage shadertype. Furthermore, all values in indices must be less than the value of
       GL_ACTIVE_SUBROUTINES for the shader stage.

GL_INVALID_OPERATION is generated if no program object is current.

       GL_INVALID_VALUE is generated if count is not equal to the value of
       GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the shader stage shadertype of the current program.

       GL_INVALID_VALUE is generated if any value in indices is geater than or equal to the value of
       GL_ACTIVE_SUBROUTINES for the shader stage shadertype of the current program.

       GL_INVALID_ENUM is generated if shadertype is not one of the accepted values.

       glUniformSubroutines - load active subroutine uniforms

shadertype
           Specifies the shader stage from which to query for subroutine uniform index.  shadertype must be one
           of GL_VERTEX_SHADER, GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER, GL_GEOMETRY_SHADER or
           GL_FRAGMENT_SHADER.

       count
           Specifies the number of uniform indices stored in indices.

       indices
           Specifies the address of an array holding the indices to load into the shader subroutine variables.
