It seems that Poppler also disables hinting completely. I created test
packages in a special PPA that enable both slight hinting, which really
improves vertical text contrast, and the default LCD filter, which
improves horizontal contrast a great deal.

I had to revert the removal of the FreeType LCD filtering API in Cairo
1.7.6 so that Tom’s patch still works as intended. The PPA sources can
be found here:

The attachment shows one example of the effect of slight hinting and the 
subpixel LCD filter.
Please test, you will see that in most cases it improves readability, but for 
some (thin) fonts and zoom levels, there’s also color fringing.

filter"
