[cairo] toy text api, fonts and scales

[Mikhail Kozhevnikov]

Hi,

I'm experiencing troubles with rendering text to PDF at different scales 
with cairo_show_text().

The labels are displayed with always the same font family and size 
("Sans Serif", 0.3), but as the scale value changes, intervals between 
symbols stretch enormously - up to 10 times the width of a letter.

Anyone met the same? What could be the reason?

Thanks, Mikhail.
