+/**
+ * Public EGL API entrypoints
+ *
+ * Generally, we use the EGLDisplay parameter as a key to lookup the
+ * appropriate device driver handle, then jump though the driver's
+ * dispatch table to handle the function.
+ *
+ * That allows us the option of supporting multiple, simultaneous,
+ * heterogeneous hardware devices in the future.
+ *
+ * The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
+ * opaque handles implemented with 32-bit unsigned integers.
+ * It's up to the driver function or fallback function to look up the
+ * handle and get an object.
+ * By using opaque handles, we leave open the possibility of having
+ * indirect rendering in the future, like GLX.
+ *
+ *
+ * Notes on naming conventions:
+ *
+ * eglFooBar - public EGL function
+ * EGL_FOO_BAR - public EGL token
+ * EGLDatatype - public EGL datatype
+ *
+ * _eglFooBar - private EGL function
+ * _EGLDatatype - private EGL datatype, typedef'd struct
+ * _egl_struct - private EGL struct, non-typedef'd
+ *
