main: set_tex_parameteri now handles errors according to the OpenGL 4.5 Specification.
Beginning in the OpenGL 4.3 core specification, some error handling has changed (see OpenGL 4.5 core spec, 30.10.2014, Section 8.10 Texture Parameters, pages 228-29). As an example, changing sampler states with a multisample target throws INVALID_ENUM rather than INVALID_OPERATION. Reviewed-by: Anuj Phogat <anuj.phogat@gmail.com>
