# A rounded fill drawn the way the non-native theme draws scrollbar thumbs: a
# border whose top/bottom widths are 0.6 of the height, so they overlap and the
# whole shape is four corner segments clipped to their own quadrant, meeting at
# the rect's vertical midpoint. The height is odd, so that midpoint is a half
# pixel, and the bound reference-frame transform puts the shape at a sub-pixel
# offset that WebRender snaps back out.
#
# The two neighbouring clips must describe that midpoint identically: they are
# non-antialiased on the shared edge, so a one-ULP disagreement rounds them apart
# and drops a whole device pixel row out of the shape (bug 2059620).
