  Message : 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); BUG=angleproject:2890 TEST=angle_end2end_tests.TextureBorderClamp* Change-Id: Iee3eeb399d8d7851b3b30694ad8f21a2111f5828 Reviewed-on: https://chromium-review.googlesource.com/c/1257824 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
