Minecraft wiki entry for Animation_placeholder_texture, associated text: It is worth noting here that flowing liquids use a texture twice the size of most block textures (32x32 as opposed to the usual 16x16). This is not unique to placeholder textures, and can also be noted when viewing the raw textures for liquids in 13w02a[more information needed] and above, as well as applying internally for generated liquid textures. A larger texture is used here since the texture is rotated accordingly to match the flow direction, while otherwise remaining at the same resolution. As a result, 16x16 textures would be too small to show a continuous texture if rotated at all, as with the most extreme case, a 45 degree rotation, there would be clear gaps at the corners, as one corner to the other would cross 16√2 pixels rather than 16.[verify]
