Subject: mesa: Change OES_standard_derivatives to be stand-alone extension
X-Git-Tag: mesa-7.11-rc1~2747
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=78838b2d1bd88f948030cd60479b832b661ccd3c;p=platform%2Fupstream%2Fmesa.git

mesa: Change OES_standard_derivatives to be stand-alone extension

Add a bit in struct gl_extensions for OES_standard_derivatives, and enable
the bit by default. Advertise the extension only if the bit is enabled.

Previously, OES_standard_derivatives was advertised in GLES2 contexts
if ARB_framebuffer_object was enabled.
