How to do this in druid?
like some measure text function in some 2d graphic lib.
this feature needed by developing complex rich text app like ms word.
return non-mono char width, font height, ascent, descent, baseline etc.

we don't provide direct access to character information, and the actual visible bounds of a glyph may not correspond to the reported layout metrics.

You can get this information the usual way, though, by creating a TextLayout and then accessing metrics through the methods on that object.
