    """A structure holding the state and timing of the framerate manager.

    This class can be used with other SDL_gfx functions to set a custom
    framerate within a given rendering loop. When used with
    :func:`SDL_framerateDelay`, it uses its initial frame onset time
    (:attr:`baseticks`) and the duration per frame to try to present frames
    at consistent intervals from that initial point.

    After an FPSManager is created, it needs to be initialized with
    :func:`SDL_initFramerate` before it can be used.

    .. note::
        This method of frame pacing may not play nicely with vsync in SDL2.

    Attributes:
        framecount (int): The number of frames counted by the manager since
            being initialized.
        rateticks (float): The time delay (in ms) between each frame.
        baseticks (int): The milliseconds since SDL initialization at which the
            manager was initialized with :func:`SDL_initFramerate`. Used
            internally as the initial frame onset time.
        lastticks (int): The milliseconds since SDL initialization at which the
            previous frame was displayed.
        rate (int): The framerate (in Hz) of the manager.

def gfxPrimitivesSetFont(fontdata, cw, ch):

    The SDL_gfx library uses its own special format for bitmap fonts. Basically,
    fonts are byte arrays where each glyph is made up of the same number of
    bytes (as defined by the ``cw`` and ``ch`` arguments). The bytes are used as
    a binary bitmask with 1s indicating the pixels of the character and 0s
    indicating the transparent background. For example, the following is the
    definition of the capital H glyph in the default font:

    .. code-block:: c

       /*
       * 72 0x48 'H' 
       */
       0xc6,			/* 11000110 */
       0xc6,			/* 11000110 */
       0xc6,			/* 11000110 */
       0xfe,			/* 11111110 */
       0xc6,			/* 11000110 */
       0xc6,			/* 11000110 */
       0xc6,			/* 11000110 */
       0x00,			/* 00000000 */

    Each font must contain glyphs for all 256 ASCII characters. Since this is
    a pretty painful format for defining your own fonts, you can load and use
    any of the predefined SDL_gfx fonts from the following link:
    https://github.com/ferzkopp/SDL_gfx/tree/master/Fonts

    If no font has been set, SDL_gfx defaults to rendering with a built-in 8x8
    pixel font.

    .. note::

        the SDL_gfx format, please let us know! That would be incredibly cool
