How to read theme values. in custom visuals

[superspandl]

Hello,

I'm trying to get the values from a theme within a custom visual.

I can get the color settings with the `ColorHelper`, but how can I get values about font family, size, and colors?

If I look into this sample theme:

https://gist.github.com/gonz4lex/7097bc0a7c6b40a7067a065965ad6414

or
https://github.com/mattrudy/PowerBI-ThemeTemplates/blob/master/GlobalLevelTemplate.json

Multiple values could be defaults for custom visuals (color, font family, alignment for labels and titles, even background color, transparency, or border radius).

Two questions:

1. Is there a way to get them with the API?

2. Are all these properties also present in the default theme?

Thanks

After some more research, I have the impression that there is no way to initialize a chart with values from the theme.

1. Color values are not passed to the constructor. 
2. Colors could be set the first time the update method runs, however, the colors would then be set and a change on the theme wouldn't have any impact on the chart
3. The reset to default settings would not have the same result as creating the chart

It seems that the concept of themes isn't integrated into PBI custom visuals.

Could confirm my theory?
