# A flat reference frame with a plain 2D transform sits between a perspective
# and a child with a Z translation. The flat frame must flatten the child into
# its plane before the perspective applies, so the rect renders unshrunk. Used
# to fail because a 2D flat transform did not open its own coordinate system.
