+This patch is a revert of commit 15a66d72f33a099ec65e0fd37cf14548ed1d2bdb (Rolling 5 dependencies and fixing build (#1057)) because it adds usage of the .maxDualSourceDrawBuffersEXT field which is not available in any tagged release of glslang. The field is added in glslang in https://github.com/KhronosGroup/glslang/commit/e05cc20ec20a154d94256c744a3837c23719c0f9
