Sergey, you should really not believe these smooth marketing brochures :-)

My Acrobat Reader comes with a file named COOLTYPE.DLL that is nearly 2 MB
in size. I assure you that this is a complete font engine, not just a
LCD-optimized rendering
technology :-)

I suspect that it includes lots of features (e.g. a small Postscript
interpreter, the ability to
convert font files to other formats, big tables to handle legacy CJK
fonts, etc...), that would
explain its size.
