Re: WPS line height patch

[Paul Louden]

I'm not for band-aid fixes, but I don't think it should be seen as
one. It adds functionality that will be useful, even with viewports.
Though you can duplicate what this patch does with viewports, it would
require that every single visible line of the WPS be defined as its
own viewport for the same effect. Converting a WPS to font-height
independence would be frustrating for a user, and add a bunch of
unnecessary tags to the WPS to define all those viewports.
