Subject: main: set_tex_parameterf now handles errors according to the OpenGL 4.5 Specification.
X-Git-Tag: upstream/17.1.0~21647
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=795ba44754d99d204dbdfd7042c839c6eae497a1;p=platform%2Fupstream%2Fmesa.git

main: set_tex_parameterf now handles errors according to the OpenGL 4.5 Specification.

Beginning in the OpenGL 4.3 core specification, certain error handling has
changed.  One example shown here is that INVALID_ENUM is thrown instead of
INVALID_OPERATION when a user attempts to set sampler parameters for a
multisample target.
