From 5a006b026de5e1a26d1de5ca635773658846ce39 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 7 Feb 2019 21:58:57 -0800 Subject: [PATCH] mesa: Advertise EXT_float_blend in ES 3.0+ contexts. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This extension simply drops a draw time restriction: "Furthermore, an INVALID_OPERATION error is generated by DrawArrays and the other drawing commands defined in section 2.8.3 (10.5 in ES 3.1) if blending is enabled (see below) and any draw buffer has 32-bit floating-point format components." We never correctly enforced this restriction anyway, so we were basically already implementing it. We just need to advertise it for our behavior to be correct. The extension requires EXT_color_buffer_float, but we already enable that via dummy_true. So we can dummy_true this one as well. Found while debugging WebGL conformance tests. Does not fix any.
