From f41be53a1706181be85a8ba41681e28b4780f6e1 Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Mon, 6 May 2019 01:58:56 +0000 Subject: [PATCH] compiler: Add enums for blend state We add enums corresponding to (GLES) blend state to shader_enums.h, complementing the existing advanced blending enums in the file. This allows us to represent blending state in a driver-agnostic, API-agnostic way to permit lowering.
