/*
* How this all works...
*
* This directory implements three different interfaces to Chromium:
*
* 1. the Chromium interface - this is defined by the functions that start
* with the "cr" prefix and are defined in chromium.h and implemented in
* stub.c. Typically, this is used by parallel apps (like psubmit).
*
* 2. GLX emulation interface - the glX*() functions are emulated here.
* When glXCreateContext() is called we may either create a real, native
* GLX context or a Chromium context (depending on match_window_title and
* mimimum_window_size).
*
* 3. WGL emulation interface - the wgl*() functions are emulated here.
* When wglCreateContext() is called we may either create a real, native
* WGL context or a Chromium context (depending on match_window_title and
* mimimum_window_size).
*
