Is it possible to change the orientation of circular tracks?

[flekschas]

I noticed that circular tracks are by default oriented counterclockwise. Is it possible to change the orientation?

On a side note, I think it might be nice to set the default to clockwise to match circos behavior.

Here's an example: https://gosling-lang.github.io/gosling.js/?full=false&spec=(XassemblyRhg19GXlayoutRcircularGXspacing40%2CXtracksNC*(-'dataK-MurlRhttps%3A%2F%2Fgist.githubusercontent.cU%2Fflekschas%2F1912fdd661851530f7389b18531c0a85%2Fraw%2FHs.hg19.T*ITMHosUeFEH'AMZFYsN'startGLend'%5D-JoverlayNS(SMmarkRrect'A*Mx_startBxe_endBcolorKS*MfEHVS**IOnal'S*)S)-%5DA'styleK'outlineWP40JsizeKD20QKD'gray'QWPKD0.5JyK%20D10%20JwP4500A'height4100C*)C%5D%0A)*%20%20-C**4!%20A%2C-BVIZ'%20)A*MC%0A*D'value4EYRG'%2CHchrUI'typeRJ)A'K4(L%20'M*'N4%5BOnUiPidthQJstrokeR4'S-*Tcsv'AUomVG%20XC'YieldZgeOc_KLfE%01_ZYXVUTSRQPONMLKJIHGEDCBA4-*_

I agree. We plan to implement the clockwise one, and I think we should use it by default.

Example of a circular track with counterclockwise axis:

{
  "layout": "circular",
  "tracks": [
    {
