This code added a second qhd abbreviation to this list; it precedes and
therefore overrides the earlier dimension of 960x540. Ticket #9591 is
about this.
According to Wikipedia, qHD is 960x540 (q stands for quarter in this
case) and QHD is 2560x1440 (Q is quad). So maybe an ad-hoc check for
this would be appropriate?
