The fontscale parameter pixelates text

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set \documentclass[landscape,a0paper,fontscale=0.1]{baposter}
2. Write some text
3. Compile and open the resulting pdf

What is the expected output? What do you see instead?

The expected output is nicely typeset text. Instead, the text is pixelated.

What version of the product are you using? On what operating system?

The September 29, 2011 version. My OS is GNU/Linux (Trisquel 6.0).

Please provide any additional information below.

I can notice pixelated text in two distinct pdf viewers as well as on an A0 
hard copy with fontscale=0.25 too.

That is probably a problem with the font you are using. It can only happen when 
you use fonts that are not described by outlines.
