Very.

pixman is not that young actually (2003), but it was built into both
cairo and Xorg until ~2007.  Unfortunately, the pixman code that is in
cairo prefixes all names with "_cairo_" (so they look like
"_cairo_pixman_image_create") and there is no public header file.  But I
don't see any reason why pixman couldn't be included in EPEL.
