<pre>It remains an issue of available precision, the rounding errors and coarseness
of glyph placement onto a pixel based screen canvas can not physically do much
better compared to the print and PDF export which have much higher precision
(and where font kerning is functional).
Addressing bug 10332 would allow effective sub-pixel rendering and more
appealing font kerning on displays.
Until then while substituting fonts, the 'Always' or 'Screen Only' choices on
the Tools -> Options -> Fonts 'Replacement Table' demonstrates a precedent for
handling rendering to VCL screen canvas distinct from printing/PDF generation.
I have not looked at the methods, but imagine similar mechanism could be
applied to font kerning--just a reversed sense, 'Never' or for 'Printing/PDF
Only' output. Maybe even located on the same Tools -> Fonts panel as it should
be applied globally.</pre>
