arbitrary GetInput (object obj, void shader_input, int index )

Return Value: value of the input at index

Arguments:

Gets the value of a shader's input. You tell messiah which input you wish to adjust by sepcifing an index value, you should have previously stored this value as returned by fxShaderCreateInput. Both the obj and the shader_input values are passed to your shader function by messiah, if messiah doesn't pass these values to a particular function it should be assumed that it is not safe to call this function from there.
