-- | Generic functions for manipulating paragraph layout.
--
-- In order to create such paragraph layout in the first place, see
-- "Data.Text.ParagraphLayout.Rich" for the rich text interface, or
-- "Data.Text.ParagraphLayout.Plain" for the legacy plain text interface.
--
-- Positions and distances are represented as 32-bit integers. Their unit must
-- be defined by the caller, who must calculate the desired dimensions of the
-- EM square of the input font and set them using
-- `Data.Text.Glyphize.optionScale`.
--
-- For example, if @1em = 20px@, if the output pixels are square, and if the
-- output coordinates are in 1/64ths of a pixel, you should set the scale to
-- @`Just` (1280, 1280)@.
--
-- X coordinates increase from left to right.
--
-- Y coordinates increase from bottom to top.
