Package: libgl1-mesa-dri Severity: wishlist I suggest adding a recommends dependency to mesa-dri for the package libtxc-dxtn0 provided by libtxc-dxtn-s2tc0. The package is currenly available in unstable S2TC is a most likely patent-free S3TC compatible texture compression. The performance increase for GL and WebGL applications offering this option is quite noticable.
