Currently, many trace objects have a default ```alpha=0.8```, to allow traces below the top-layer trace to shine through somewhat. This can lead to undesirable behavior if there is only one trace, however, as it leads to less than totally black lineplots. Perhaps tile should be smarted about this, and set alpha to 0.8 if there are lines layered beneath the present line, and to 1.0 otherwise.

And for some primitive traces, alpha should probably be 1.0 by default, instead of the present 0.8.

The alpha for polygons, and for polyalpha (the shaded confidence interval in lineplots) should stay at 0.8, regardless.
