Previously sampling depth investigation #659.
Currently on vulkan many devices (mostly desktop) support VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT depth. See https://vulkan.gpuinfo.org/listoptimaltilingformats.php?platform=all.
D3D12 and macOS and Apple9+ (though depth16unorm filter only requires Apple2+ https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf) also support filtering depth.
