Q:

What text rendering library Chrome uses for Linux?

Are they using freetype or xfonts or cairo or something else? Maybe their own made library? I am thinking to use the same library in my program as well. I think what Google uses will be well maintained for long time.

A:

Chrome uses Skia for nearly all graphics operations, including text
  rendering. GDI is for the most part only used for native theme
  rendering; new code should use Skia.

Skia is a complete 2D graphic library for drawing Text, Geometries, and Images.
