Context for some ticks scriptable options

[stockiNail]

I noticed that the following properties in the ticks options for radial linear scale are scriptable

• count
• format
• maxTicksLimit
• precision
• stepSize

and the invoked callbacks are receiving a chart context as argument.
Maybe this is implemented by design but it could make more sense to pass a scale context due to the ticks options is a sub element of scale options.

Yes, those should likely use the scale context. I'd support updating this
