Struct TouchHandle 

pub struct TouchHandle;

The grab handle at one end of a touch selection: a bar down the caret line with a knob at its outer end, the start’s above and the end’s below.

Base paints the handle where it belongs in the paint order — inside the text that owns the selection, so that whatever covers the text covers the handle — and only with the selection’s own color. Its shape is the one every platform draws; a styled layer supplies the color.
