+ * @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.
+ *
+ * FT_LOAD_TARGET_NORMAL ::
+ * Use hinting for @FT_RENDER_MODE_NORMAL.
+ *
+ * FT_LOAD_TARGET_LIGHT ::
+ * Use hinting for @FT_RENDER_MODE_LIGHT.
