+  * @enum:
+  *   FT_LOAD_XXX
+  *
+  * @description:
+  *   A list of bit-field constants, used with @FT_Load_Glyph to indicate
+  *   what kind of operations to perform during glyph loading.
+  *
+  * @values:
+  *   FT_LOAD_DEFAULT ::
+  *     Corresponding to 0, this value is used a default glyph load.  In this
+  *     case, the following will happen:
+  *
+  *     1. FreeType looks for a bitmap for the glyph corresponding to the
+  *        face's current size.  If one is found, the function returns.  The
+  *        bitmap data can be accessed from the glyph slot (see note below).
+  *
+  *     2. If no embedded bitmap is searched or found, FreeType looks for a
+  *        scalable outline.  If one is found, it is loaded from the font
+  *        file, scaled to device pixels, then "hinted" to the pixel grid in
+  *        order to optimize it.  The outline data can be accessed from the
+  *        glyph slot (see note below).
+  *
+  *     Note that by default, the glyph loader doesn't render outlines into
+  *     bitmaps.  The following flags are used to modify this default
+  *     behaviour to more specific and useful cases.
+  *
+  *   FT_LOAD_NO_SCALE ::
+  *     Don't scale the vector outline being loaded to 26.6 fractional
+  *     pixels, but kept in font units.  Note that this also disables
+  *     hinting and the loading of embedded bitmaps.  You should only use it
+  *     when you want to retrieve the original glyph outlines in font units.
+  *
+  *   FT_LOAD_NO_HINTING ::
+  *     Don't hint glyph outlines after their scaling to device pixels.
+  *     This generally generates "blurrier" glyphs in anti-aliased modes.
+  *
+  *     This flag is ignored if @FT_LOAD_NO_SCALE is set.
+  *
+  *   FT_LOAD_RENDER ::
+  *     Render the glyph outline immediately into a bitmap before the glyph
+  *     loader returns.  By default, the glyph is rendered for the
+  *     @FT_RENDER_MODE_NORMAL mode, which corresponds to 8-bit anti-aliased
+  *     bitmaps using 256 opacity levels.  You can use either
+  *     @FT_LOAD_TARGET_MONO or @FT_LOAD_MONOCHROME to render 1-bit
+  *     monochrome bitmaps.
+  *
+  *     This flag is ignored if @FT_LOAD_NO_SCALE is set.
+  *
+  *   FT_LOAD_NO_BITMAP ::
+  *     Don't look for bitmaps when loading the glyph.  Only scalable
+  *     outlines will be loaded when available, and scaled, hinted, or
+  *     rendered depending on other bit flags.
+  *
+  *     This does not prevent you from rendering outlines to bitmaps
+  *     with @FT_LOAD_RENDER, however.
+  *
+  *   FT_LOAD_VERTICAL_LAYOUT ::
+  *     Prepare the glyph image for vertical text layout.  This basically
+  *     means that `face.glyph.advance' will correspond to the vertical
+  *     advance height (instead of the default horizontal advance width),
+  *     and that the glyph image will be translated to match the vertical
+  *     bearings positions.
+  *
+  *   FT_LOAD_FORCE_AUTOHINT ::
+  *     Force the use of the FreeType auto-hinter when a glyph outline is
+  *     loaded.  You shouldn't need this in a typical application, since it
+  *     is mostly used to experiment with its algorithm.
+  *
+  *   FT_LOAD_CROP_BITMAP ::
+  *     Indicates that the glyph loader should try to crop the bitmap (i.e.,
+  *     remove all space around its black bits) when loading it.  This is
+  *     only useful when loading embedded bitmaps in certain fonts, since
+  *     bitmaps rendered with @FT_LOAD_RENDER are always cropped by default.
+  *
+  *   FT_LOAD_PEDANTIC ::
+  *     Indicates that the glyph loader should perform pedantic
+  *     verifications during glyph loading, rejecting invalid fonts.  This
+  *     is mostly used to detect broken glyphs in fonts.  By default,
+  *     FreeType tries to handle broken fonts also.
+  *
+  *   FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
+  *     Indicates that the glyph loader should ignore the global advance
+  *     width defined in the font.  As far as we know, this is only used by
+  *     the X-TrueType font server, in order to deal correctly with the
+  *     incorrect metrics contained in DynaLab's TrueType CJK fonts.
+  *
+  *   FT_LOAD_NO_RECURSE ::
+  *     This flag is only used internally.  It merely indicates that the
+  *     glyph loader should not load composite glyphs recursively.  Instead,
+  *     it should set the `num_subglyph' and `subglyphs' values of the glyph
+  *     slot accordingly, and set "glyph->format" to
+  *     @FT_GLYPH_FORMAT_COMPOSITE.
+  *
+  *     The description of sub-glyphs is not available to client
+  *     applications for now.
+  *
+  *   FT_LOAD_IGNORE_TRANSFORM ::
+  *     Indicates that the glyph loader should not try to transform the
+  *     loaded glyph image.  This doesn't prevent scaling, hinting, or
+  *     rendering.
+  *
+  *   FT_LOAD_MONOCHROME ::
+  *     This flag is used with @FT_LOAD_RENDER to indicate that you want
+  *     to render a 1-bit monochrome glyph bitmap from a vectorial outline.
+  *
+  *     Note that this has no effect on the hinting algorithm used by the
+  *     glyph loader.  You should better use @FT_LOAD_TARGET_MONO if you
+  *     want to render monochrome-optimized glyph images instead.
+  *
+  *   FT_LOAD_LINEAR_DESIGN ::
+  *     Return the linearly scaled metrics expressed in original font units
+  *     instead of the default 16.16 pixel values.
+  *
+  *   FT_LOAD_NO_AUTOHINT ::
+  *     Indicates that the auto-hinter should never be used to hint glyph
+  *     outlines.  This doesn't prevent native format-specific hinters from
+  *     being used.  This can be important for certain fonts where unhinted
+  *     output is better than auto-hinted one.
