   2  * Public EGL API entrypoints
   3  *
   4  * Generally, we use the EGLDisplay parameter as a key to lookup the
   5  * appropriate device driver handle, then jump though the driver's
   6  * dispatch table to handle the function.
   7  *
   8  * That allows us the option of supporting multiple, simultaneous,
   9  * heterogeneous hardware devices in the future.
  10  *
  11  * The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
  12  * opaque handles. Internal objects are linked to a display to
  13  * create the handles.
  14  *
  15  * For each public API entry point, the opaque handles are looked up
  16  * before being dispatched to the drivers.  When it fails to look up
  17  * a handle, one of
  18  *
  19  * EGL_BAD_DISPLAY
  20  * EGL_BAD_CONFIG
  21  * EGL_BAD_CONTEXT
  22  * EGL_BAD_SURFACE
  23  * EGL_BAD_SCREEN_MESA
  24  * EGL_BAD_MODE_MESA
  25  *
  26  * is generated and the driver function is not called. An
  27  * uninitialized EGLDisplay has no driver associated with it. When
  28  * such display is detected,
  29  *
  30  * EGL_NOT_INITIALIZED
  31  *
  32  * is generated.
  33  *
  34  * Some of the entry points use current display, context, or surface
  35  * implicitly.  For such entry points, the implicit objects are also
  36  * checked before calling the driver function.  Other than the
  37  * errors listed above,
  38  *
  39  * EGL_BAD_CURRENT_SURFACE
  40  *
  41  * may also be generated.
  42  *
  43  * Notes on naming conventions:
  44  *
  45  * eglFooBar    - public EGL function
  46  * EGL_FOO_BAR  - public EGL token
  47  * EGLDatatype  - public EGL datatype
  48  *
  49  * _eglFooBar   - private EGL function
  50  * _EGLDatatype - private EGL datatype, typedef'd struct
  51  * _egl_struct  - private EGL struct, non-typedef'd
  52  *
