Added visual test for multi-line label alignment. Calculation of label alignment in multi-line labels seems to be off. This test reproduces it by laying out a series of multi-line labels along an S-shaped curve. In all these cases, the vertical bar character should, to within a few pixels, line up. The orientation at sharper corners is still a little off, but likely due to discontinuities.
