Scattergl fill tozerox/y doesn't work as expected #1334
Description
scattergl fill tozeroy fills to lowest y value rather than 0 and behaves inconsistently from scatter fill which uses the trace as a bound (see codepen: http://codepen.io/plotly/pen/apyXpW?editors=1010 )
Additionally, we need to fix the attribute description for scattergl fill - it should be different from scatter's fill.

Also, the "toself" fill option doesn't work as expected. The enclosed area isn't filled.

Yes, regl-line2d is capable of filling any shapes now, so fully svg-compatible in that sense. We can cover these cases.

@dfcreative 's regl-based
scatterglwork will get us very close to parity with SVGscatter.I found a few discrepancies:

@etpinard 3b08da1 should fix both. Although https://rreusser.github.io/plotly-mock-viewer/#scatter_fill_no_opacity does not fail now, it requires detailed consideration. I get
although regular
scattergives (the case of creased shape)I guess that should be addressed in a separate issue.

I'm going to close this thing as the issue title refers to to-zero fills which are fixed in #2258
For more fill open items, see #130
