/**
* 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. Internal objects are linked to a display to
* create the handles.
*
* For each public API entry point, the opaque handles are looked up
* before being dispatched to the drivers. When it fails to look up
* a handle, one of
*
* EGL_BAD_DISPLAY
* EGL_BAD_CONFIG
* EGL_BAD_CONTEXT
* EGL_BAD_SURFACE
* EGL_BAD_SCREEN_MESA
* EGL_BAD_MODE_MESA
*
* is generated and the driver function is not called. An
* uninitialized EGLDisplay has no driver associated with it. When
* such display is detected,
*
* EGL_NOT_INITIALIZED
*
* is generated.
*
* Some of the entry points use current display, context, or surface
* implicitly. For such entry points, the implicit objects are also
* checked before calling the driver function. Other than the
* errors listed above,
*
* EGL_BAD_CURRENT_SURFACE
*
* may also be generated.
*
* 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
*
