# Bug 1950029: under a transform that makes a 1px border a fractional device
# thickness (here scale(1.5) -> 1.5 device px), the four sides land at
# different sub-pixel phases and render with visibly uneven thickness (right
# and bottom look thicker than left and top). The edge thickness must be
# snapped to a whole device pixel so every side is a consistent width. With
# transform-origin at 0,0 the outer box lands on integer device pixels
# (20,20)-(120,120) -> (30,30)-(180,180), and the 1.5px edges snap to 2px.
