"""
What do we want to check?
=========================
* any text objects that are not converted to a path?
* can be implemented as tag blacklist
* any outlines? they need to be converted to paths
* check for crossing paths
* this is the hardest
* for lines, this is easy, and can, for example, be done with shapely:
>>> from shapely.geometry import LineString
>>> l1 = LineString([(0, 0), (1, 1)])
>>> l2 = LineString([(0, 1), (1, 0)])
>>> l1.intersects(l2)
True
>>> p = l1.intersection(l2)
>>> p.x
0.5
>>> p.y
0.5
* check for self-intersection, too (=> line.is_simple)
* need to split each complex subpath into its segments
* then, when doing intersections, remove the `boundary`
from the intersection set, because two adjacent
segments from a subpath always intersect in their boundary
* handle the commands M, Z, L, C, Q, A (parsed via simplepath)
* M: moveto
* Z: closepath (straight closing line)
* L: lineto
* C: curveto (cubic bezier)
* Q: curveto (quadratic bezier)
* A: elliptical arc (circles, ellipsis)
* paths need to have a minimum distance to other paths
* if two paths are connected ("T-junction"), this junction needs to be
exempt from the distance check.
