/*
|
|
* The bug appears to be triggered if:
|
|
* 1. There is more than one subpath
|
|
* 2. All subpaths are axis-aligned rectangles
|
|
* 3. Only one of the subpaths is within surface bounds
|
|
*
|
|
* Tweaking any of the coordinates so that there is at least one
|
|
* non-axis-aligned segment or removing the second subpath (the one that is
|
|
* outside the surface bounds) causes the bug to disappear.
