Transforms for all traces?

[dmt0]

Just work:

• * box,
• * violin,
• * ohlc,
• * candlestick,

Seem straightforward, no 2d inputs:

• * scatterternary
• * scatterpolar
• * scatter3d
• * scattergeo
• * histogram2d

Will not work (because they must have 2d inputs):

• mesh3d
• surface
• contour
• heatmap

Submitted an issue: plotly/plotly.js#2908

contour and heatmap always have 2d input so they're out, but histogram2d actually doesn't accept 2d input, despite the name.
