You need to check info->src.box.height == info->dst.box.height as well.

Missing space between operator and operand.

Even with that fixed, this change breaks a number of scissor related
piglit tests because it ignores info->scissor{_enable,}. You need to
either fall back or factor in info->scissor if info->scissor_enable is on.
Might be safer to fall back for info->render_condition_enable as well.
