 /**
  * \file imports.c
  * Standard C library function wrappers.
  * 
  * Imports are services which the device driver or window system or
  * operating system provides to the core renderer.  The core renderer (Mesa)
  * will call these functions in order to do memory allocation, simple I/O,
  * etc.
  *
  * Some drivers will want to override/replace this file with something
