From fd27fb511386615cd6b44b037f9f5117846b51d4 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Mon, 3 Feb 2020 18:22:31 +0100 Subject: [PATCH] st/mesa: use uint-result for sampling stencil buffers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Otherwise, we end up mismatching the result-type and the sampler-type.
