Taxi route lines drew tiled copies beside each line. benilla chose repeat or clamp from a texture's current UVs. Lua-set textures with UVs past [0,1] tiled.
In 1.12.1 the wrap is fixed when the file loads (`0x770200`, both axes, sampler table `0x80a254`: clamp or wrap). An XML `<Texture>` passes 1 only when its own `<TexCoords>` leave [0,1] (`0x76fe20`, each template level with its own flag). Lua `SetTexture` passes 0 (`0x79bda5`). `SetTexCoord` never changes it. A backdrop's background follows `tile`, its sides wrap, its corners clamp. A same-file call keeps the loaded texture (`0x770225`).
Now each texture carries its load-time flag and the sampler follows it. Route lines draw as one line. The stance bar's middle strip clamps, as its XML loads it.
Tests: the Lua, XML, template, same-file and backdrop flags, and the sampler pick.
