+  *

+  * @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.

+  * @description:

+  *   open a new stream to parse gzip-compressed font files. This is

+  *   mainly used to support the compressed *.pcf.gz fonts that come

+  *   with XFree86

+  *

+  * @input:

+  *   stream :: target embedding stream

+  *   source :: source stream, used to

+  *

+  * @return:

+  *   error code. 0 means success

+  *

+  * @note:

+  *   the source stream must be opened _before_ calling this function.

+  *

+  *   calling @FT_Stream_Close on the new stream will *not* call

+  *   @FT_Stream_Close on the source stream. None of the stream objects

+  *   will be released to the heap.

+  *

+  *   the stream implementation is very basic, and resets the decompression

+  *   process each time seeking backwards is needed within the stream

+  *

+  *   in certain builds of the library, gzip compression recognition is

+  *   automatic when calling @FT_New_Face or @FT_Open_Face. This means that

+  *   if no font driver is capable of handling the raw compressed file,

+  *   the library will try to open a gzip stream from it and re-open

+  *   the face with it.

+  *

+  *   this function may return "FT_Err_Unimplemented" if your build of

+  *   FreeType was not compiled with zlib support.
