Phantom points are not scaled like ordinary points.

e.g. VGA (=96 dpi) and a emUnit=2048 font

pointSize = 8 (mppem = 11):
	550	->	128
	745	->	256
	862	->	256
	930	->	320
	940	->	320
	1117	->	384
	1177	->	384
	1295	->	?
	1302	->	448
	1400	->	512 !
	1488	->	512
	1578	->	512
	1588	->	576 !
	1672	->	576
	1676	->	576
	2048	->	704
