"""
Given an SVG as a Python ElementTree, return a set of straight line
segments which approximate the outlines in that SVG when rendered.
Occlusion is not accounted for in the returned list of outlines. Even if
one shape is completely occluded by another, both of their outlines will be
reported. Simillarly, overlapping lines will also be passed through.
.. note::
This function internally uses the QSvg library from Qt to render the
provided SVG to a special painting backend which captures the output
lines. As a consequence, SVG feature support is as good or as bad as
that library. QSvg is generally regarded as a high quality and
relatively complete SVG implementation and so most SVG features should
be supported.
.. note::
Due to its internal use of Qt, a PySide2.QtGui.QGuiApplication will be
created if one has not already been created. Non-Qt users and most Qt
users should not be affected by this.
Parameters
----------
root : ElementTree
The SVG whose outlines should be extracted.
width_mm, height_mm : float or None
The page size to render the SVG at (in milimeters). If omitted, this
will be determined automatically from the SVG's width and height
attributes. These arguments are mandatory for SVGs lacking these
attributes.
pixels_per_mm : float
Curved outlines will be approximated by straight lines in the output.
This parameter controls how exactly curves will be approximated.
Specifically, the curve approximation will be at least fine enough for
rasterised versions of the lines to 'look right' at the specified pixel
density.
Returns
-------
[((r, g, b, a) or None, width, [(x, y), ...]), ...]
A list of polylines described by (colour, line) pairs.
The 'colour' values define the colour used to draw the line (if a solid
colour was used) or None (if a gradient or patterned stroke was used).
Colours are given as four-tuples in RGBA order with values from 0.0 to
1.0.
The 'width' value gives the line width used to draw the line (given in
mm). If the shape being drawn has a non-uniform scaling applied, this
value may not be meaningful and its actual value should be considered
undefined.
The 'line' part of each tuple defines the outline as a series of (x, y)
coordinates (given in mm) which describe a continuous polyline. These
polylines may be considered open. Closed lines in the input SVG will
result in polylines where the first and last coordinate are identical.
Lines may go beyond the bounds of the designated page size (as in the
input SVG).
