[Mesa-dev] [PATCH] mesa/main: Advertise ARB_polygon_offset_clamp.

[Ilia Mirkin]

OK, well, I don't know what our policy is on adding unpublished
extensions. However I've yet to see an ARB extension that says it's
available in GL ES contexts, so at the very least you'd have to
replace ES1, ES2 with x's.

Someone with access to the spec will have to do a proper review of this though.

Cheers,
