  Support GL_OES_texture_border_clamp
  
  Added support for GL_TEXTURE_BORDER_COLOR and GL_CLAMP_TO_BORDER in
  OpenGL/OpenGLES, Direct3D9 and Direct3D11 backends.
  For integer textures in OpenGLES3 contexts these additional entry points
  are available now:
  
  void glTexParameterIivOES(enum target, enum pname, const int *params);
  void glTexParameterIuivOES(enum target, enum pname, const uint *params);
  
  void glGetTexParameterIivOES(enum target, enum pname, int *params);
  void glGetTexParameterIuivOES(enum target, enum pname, uint *params);
  
  void glSamplerParameterIivOES(uint sampler, enum pname, const int *params);
  void glSamplerParameterIuivOES(uint sampler, enum pname, const uint *params);
  
  void glGetSamplerParameterIivOES(uint sampler, enum pname, int *params);
  void glGetSamplerParameterIuivOES(uint sampler, enum pname, uint *params);
