 Cairo is designed to produce consistent output on all output media while
 taking advantage of display hardware acceleration when available

 The cairo API provides operations similar to the drawing operators of
 PostScript and PDF.  Operations in cairo including stroking and filling cubic
 Bézier splines, transforming and compositing translucent images, and
 antialiased text rendering.  All drawing operations can be transformed by any
 affine transformation (scale, rotation, shear, etc.).")

-Fixes a crash when using freetype >= 2.9

-own memory allocator, which is not compatible with system free(), making
-this a remotely triggerable denial of service or memory corruption.]
