Shaders: initial implementation of a line shader. The shader requires the input data to be laid out in a rather specific way, and there will be a dedicated MeshTools utility for it in the following commits. For independence though, the shader tests use a custom helper. The initial implementation has certain corner cases which will be eventually resolved. For now they are pinned down with repro cases in the test. But apart from that, it's pretty much usable in practice. Remaining join styles (round and miter-clip) as well as stipple support will eventually follow as well.
