+Subject: [PATCH] gl-shaders: Remove asserts relying on shader compiler
+ behavior
+
+yuv_coefficients and yuv_offsets should get optimized away by shader
+compilers as the related code paths can never be reached. This seems to
+work well on Mesa but not necessarily with other drivers.
+
+While on it, assert that the uniforms *are* present, unless the
+yuv-to-rgb conversion is handled by the driver.
+
+Upstream-Status: Backport [https://gitlab.freedesktop.org/wayland/weston/-/commit/5c49563ef49a502a6b8fae44f8778e109d32c2d9]
