 /* The following compile-time options are supported:
  *
  *     TB_OPT_ATTR_W: Integer width of `fg` and `bg` attributes. Valid values
  *                    (assuming system support) are 16, 32, and 64. (See
  *                    `uintattr_t`). 32 or 64 enables output mode
  *                    `TB_OUTPUT_TRUECOLOR`. 64 enables additional style
  *                    attributes. (See `tb_set_output_mode`.) Larger values
  *                    consume more memory in exchange for more features.
  *                    Defaults to 16.
  *
  *        TB_OPT_EGC: If set, enable extended grapheme cluster support
  *                    (`tb_extend_cell`, `tb_set_cell_ex`). Consumes more
  *                    memory. Defaults off.
  *
  * TB_OPT_PRINTF_BUF: Write buffer size for printf operations. Represents the
  *                    largest string that can be sent in one call to
  *                    `tb_print*` and `tb_send*` functions. Defaults to 4096.
  *
  *   TB_OPT_READ_BUF: Read buffer size for tty reads. Defaults to 64.
  *
  * TB_OPT_LIBC_WCHAR: If set, use libc's `wcwidth(3)`, `iswprint(3)`, etc
  *                    instead of the built-in Unicode-aware versions. Note,
  *                    libc's are locale-dependent and the caller must
  *                    `setlocale(3)` `LC_CTYPE` to UTF-8. Defaults to built-in.
  *
  *  TB_OPT_TRUECOLOR: Deprecated. Sets TB_OPT_ATTR_W to 32 if not already set.

 /* A cell in a 2d grid representing the terminal screen.
  *
  * The terminal screen is represented as 2d array of cells. The structure is
  * optimized for dealing with single-width (`wcwidth==1`) Unicode codepoints,
  * however some support for grapheme clusters (e.g., combining diacritical
  * marks) and wide codepoints (e.g., Hiragana) is provided through `ech`,
  * `nech`, and `cech` via `tb_set_cell_ex`. `ech` is only valid when `nech>0`,
  * otherwise `ch` is used.
  *
  * For non-single-width codepoints, given `N=wcwidth(ch)/wcswidth(ech)`:
  *
  * when `N==0`: termbox forces a single-width cell. Callers should avoid this
  *              if aiming to render text accurately. Callers may use
  *              `tb_set_cell_ex` or `tb_print*` to render `N==0` combining
  *              characters.
  *
  *  when `N>1`: termbox zeroes out the following `N-1` cells and skips sending
  *              them to the tty. So, e.g., if the caller sets `x=0,y=0` to an
  *              `N==2` codepoint, the caller's next set should be at `x=2,y=0`.
  *              Anything set at `x=1,y=0` will be ignored. If there are not
  *              enough columns remaining on the line to render `N` width, spaces
  *              are sent instead.
  *
  * See `tb_present` for implementation.

 /* Set the output mode. Termbox has multiple output modes:
  *
  * 1. `TB_OUTPUT_NORMAL`     => [0..8]
  *
  *    This mode provides 8 different colors:
  *      `TB_BLACK`, `TB_RED`, `TB_GREEN`, `TB_YELLOW`,
  *      `TB_BLUE`, `TB_MAGENTA`, `TB_CYAN`, `TB_WHITE`
  *
  *    Plus `TB_DEFAULT` which skips sending a color code (i.e., uses the
  *    terminal's default color).
  *
  *    Colors (including `TB_DEFAULT`) may be bitwise OR'd with attributes:
  *      `TB_BOLD`, `TB_UNDERLINE`, `TB_REVERSE`, `TB_ITALIC`, `TB_BLINK`,
  *      `TB_BRIGHT`, `TB_DIM`
  *
  *    The following style attributes are also available if compiled with
  *    `TB_OPT_ATTR_W` set to 64:
  *      `TB_STRIKEOUT`, `TB_UNDERLINE_2`, `TB_OVERLINE`, `TB_INVISIBLE`
  *
  *    As in all modes, the value 0 is interpreted as `TB_DEFAULT` for
  *    convenience.
  *
  *    Some notes: `TB_REVERSE` and `TB_BRIGHT` can be applied as either `fg` or
  *    `bg` attributes for the same effect. The rest of the attributes apply to
  *    `fg` only and are ignored as `bg` attributes.
  *
  *    Example usage: `tb_set_cell(x, y, '@', TB_BLACK | TB_BOLD, TB_RED)`
  *
  * 2. `TB_OUTPUT_256`        => [0..255] + `TB_HI_BLACK`
  *
  *    In this mode you get 256 distinct colors (plus default):
  *                0x00   (1): `TB_DEFAULT`
  *       `TB_HI_BLACK`   (1): `TB_BLACK` in `TB_OUTPUT_NORMAL`
  *          0x01..0x07   (7): the next 7 colors as in `TB_OUTPUT_NORMAL`
  *          0x08..0x0f   (8): bright versions of the above
  *          0x10..0xe7 (216): 216 different colors
  *          0xe8..0xff  (24): 24 different shades of gray
  *
  *    All `TB_*` style attributes except `TB_BRIGHT` may be bitwise OR'd as in
  *    `TB_OUTPUT_NORMAL`.
  *
  *    Note `TB_HI_BLACK` must be used for black, as 0x00 represents default.
  *
  * 3. `TB_OUTPUT_216`        => [0..216]
  *
  *    This mode supports the 216-color range of `TB_OUTPUT_256` only, but you
  *    don't need to provide an offset:
  *                0x00   (1): `TB_DEFAULT`
  *          0x01..0xd8 (216): 216 different colors
  *
  * 4. `TB_OUTPUT_GRAYSCALE`  => [0..24]
  *
  *    This mode supports the 24-color range of `TB_OUTPUT_256` only, but you
  *    don't need to provide an offset:
  *                0x00   (1): `TB_DEFAULT`
  *          0x01..0x18  (24): 24 different shades of gray
  *
  * 5. `TB_OUTPUT_TRUECOLOR`  => [0x000000..0xffffff] + `TB_HI_BLACK`
  *
  *    This mode provides 24-bit color on supported terminals. The format is
  *    0xRRGGBB.
  *
  *    All `TB_*` style attributes except `TB_BRIGHT` may be bitwise OR'd as in
  *    `TB_OUTPUT_NORMAL`.
  *
  *    Note `TB_HI_BLACK` must be used for black, as 0x000000 represents default.
  *
  * To use the terminal default color (i.e., to not send an escape code), pass
  * `TB_DEFAULT`. For convenience, the value 0 is interpreted as `TB_DEFAULT` in
  * all modes.
  *
  * Note, cell attributes persist after switching output modes. Any translation
  * between, for example, `TB_OUTPUT_NORMAL`'s `TB_RED` and
  * `TB_OUTPUT_TRUECOLOR`'s 0xff0000 must be performed by the caller. Also note
  * that cells previously rendered in one mode may persist unchanged until the
  * front buffer is cleared (such as after a resize event) at which point it will
  * be re-interpreted and flushed according to the current mode. Callers may
  * invoke `tb_invalidate` if it is desirable to immediately re-interpret and
  * flush the entire screen according to the current mode.
  *
  * Note, not all terminals support all output modes, especially beyond
  * `TB_OUTPUT_NORMAL`. There is also no very reliable way to determine color
  * support dynamically. If portability is desired, callers are recommended to
  * use `TB_OUTPUT_NORMAL` or make output mode end-user configurable. The same
  * advice applies to style attributes.
  *
  * If mode is `TB_OUTPUT_CURRENT`, return the current output mode.
  *
  * The default output mode is `TB_OUTPUT_NORMAL`.
