Function scaleTheme

scaleTheme(theme: Theme, scaler: number): Theme
Convenience function to up or downscale font sizes of a Theme object. Similarly also scales relevant paddings and margins to make font sizes sit better with the overall style defaults.
```
 // Example syntax
 const chart = lightningChart().ChartXY({
     theme: scaleTheme(Themes.darkGold, 0.6) // fonts, paddings etc. will be smaller than normal
 })
```
This was designed as an easy way to adjust chart themes for mobile view (generally themes are downscaled in this case as screen space is more limited), but it can also be convenient tool to scaling general chart elements size.

  Theme object to use as a base.
