[Pkg-fonts-devel] Bug#468219: ttf-dejavu: augment font lisibility for small font size

[Ben Laenen <benlaenen@gmail.com>]

That's because at those small sizes, there are not enough pixels left to 
render all those details. In this case rendering them would make the 
characters much too wide.

TrueType fonts have a system called hinting which aligns the outlines to 
the pixels of a screen. Since we can't make those characters wider than 
1 pixel at those small sizes, we have to make them rectangular like 
that. The other option would be gray rectangles.
