The style parameter is actually nullable. Also, the documentation of the style parameter has been made explicit that `Style.Plain` is used when a `null` style is passed.
This makes it possible for encoders to output better representation
of the actual objects instead of working with chopped up segments.
* IAnsiConsole.Write now takes an IRenderable instead of segments
* Calculating cell width does no longer require a render context
* Removed RenderContext.LegacyConsole
* Removed RenderContext.Encoding
* Added Capabilities.Unicode
The bug might occur if there are wide characters such as emojis
at the end of a line. The SplitLines method mixed cell width
and text length, which might give incorrect results. This commit
makes sure that comparison and calculation is done using cell width
where it's appropriate.
This is a temporary fix for undrawable tables until we've
implemented a proper strategy. What this does is that it replaces
an undrawable table with an ellipsis (...). This should only
occur in either super big tables or deeply nested tables in a
console with a small buffer width.
