## dotplotTables

A dotplot as the display fetches, lays out and colors it, as tables:
`alignments`, each block with its span on each axis, its strand, name and
measurements, in the color the view's `color` paints it; `segments`, the
lines the plot draws in paint order, one per block, or one per CIGAR step
where a block is wide enough on screen for its CIGAR to show, each from
(`xStart`, `yStart`) to (`xEnd`, `yEnd`) in genomic coordinates on the
axis's region named by `xRegion` and `yRegion`; and `legend`, the key.
`skipped` counts the blocks neither axis places. For a host that draws
them itself, such as R through V8.
