Re: Font pixel size selection

I think the only problem here is :pixelsize=14

Fontconfig has the format:

<families>-<point sizes>:<name1>=<values1>:<name2>=<values2>

which indicates the number should be `point size', therefore the
actual on screen pixel size could be calculated as <point size>/72*dpi

However, it should also allow user to specify the pixel size directly
through something like :pixelsize=14
