From 58a67e4e0a88e52d71eef5d08df1465f7ac610ae Mon Sep 17 00:00:00 2001 From: Laszlo Agocs Date: Mon, 28 Oct 2019 16:37:57 +0100 Subject: rhi: Move to CBOR in QShader and expand the autotest Binary JSON is said to become deprecated. Therefore, add support for CBOR. Binary JSON is still supported for deserialization, so all existing .qsb files will continue to work, as long as the binaryjson feature is enabled in the Qt build. Also makes QShaderDescription comparable. This is important for tests in particular. A nice side effect of using CBOR is that .qsb files become smaller. For a typical Qt Quick material shader this can mean a reduction of 300 bytes or more.
