To maintain compatibility with pre-9.6 Org that used MathJax 2,

the following conversions take place.

|
||
The legacy \"autonumber\" option, with the value \"AMS\",
|
||
\"None\", or \"All\", becomes the \"tags\" option set to the
|
||
value \"ams\", \"none\", or \"all\", respectively.
|
||
|
||
Any legacy values of the \"scale\" option, specified as
|
||
percentage strings, become converted to unit-interval numbers.
|
||
For example, a legacy scale of \"150\" becomes a scale of 1.5.
|
||
|
||
The legacy \"linebreaks\" option, with the value \"true\" or
|
||
\"false\", becomes the \"overflow\" option set to the value
|
||
\"linebreak\" or \"overflow\", respectively.
|
||
|
||
The legacy values of the \"font\" option, namely \"TeX\",
|
||
\"STIX-Web\", \"Asana-Math\", \"Neo-Euler\", \"Gyre-Pagella\",
|
||
\"Gyre-Termes\", \"Latin-Modern\", become converted to the
|
||
corresponding MathJax 4+ font names.
