Subject: mesa: move GL_INVALID_OPERATION error to rendering call
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ad0262185420db03e8256ef20a0f5b1b1de003d8;p=mesa.git

mesa: move GL_INVALID_OPERATION error to rendering call

The validation api doesn't trigger this error so just move it to the
code called during rendering.
