Compute the layout of the given text according to a given rectangular region size, layout flags and other parameters.

Refer to `TextField:setLayout` for a description of the arguments.
The returned table contains the following fields: - x,y,w,h: Computed bounding box of the full text - lines: The number of lines used to display the text - parts: Information about individual chunks of texts.

Each table in the part field of the returned table describe the placement of chunks of text. Their fields are: - text: The text to display in this chunk - x,y,w,h: Computed bounding box of this chunk - dx,dy: Coordinates to draw this chunk at - sep: separator character that came just after this chunk in text block - line: line number this chunk belongs to

(table) = FontBase:layoutText(text,width,height,flags,letterSpacing,lineSpacing,tabSpace,breakChar)
