* FreeType is a library that provides access to glyphs in font files. It
* scales the glyph images and their metrics to a requested size, and it
* rasterizes the glyph images to produce pixel or subpixel alpha coverage
* bitmaps.
*
* Note that FreeType is _not_ a text layout engine. You have to use
* higher-level libraries like HarfBuzz, Pango, or ICU for that.
*
* Note also that FreeType does _not_ perform alpha blending or
* compositing the resulting bitmaps or pixmaps by itself. Use your

* process FreeType's output.

*
* https://docs.microsoft.com/en-us/typography/opentype/spec/colr
*
* The glyph layer data for a given glyph index, if present, provides an
* alternative, multi-color glyph representation: Instead of rendering
* the outline or bitmap with the given glyph index, glyphs with the
* indices and colors returned by this function are rendered layer by
* layer.
*
* The returned elements are ordered in the z~direction from bottom to
* top; the 'n'th element should be rendered with the associated palette
* color and blended on top of the already rendered layers (elements 0,
* 1, ..., n-1).
*
* @input:
* face ::
* A handle to the parent face object.
*
* base_glyph ::
* The glyph index the colored glyph layers are associated with.

* @inout:
* iterator ::
* An @FT_LayerIterator object. For the first call you should set

* The glyph index of the current layer.
*
* acolor_index ::
* The color index into the font face's color palette of the current
* layer. The value 0xFFFF is special; it doesn't reference a palette
* entry but indicates that the text foreground color should be used
* instead (to be set up by the application outside of FreeType).
*
* The color palette can be retrieved with @FT_Palette_Select.
*
* @return:
* Value~1 if everything is OK. If there are no more layers (or if there
* are no layers at all), value~0 gets returned. In case of an error,
* value~0 is returned also.
*
* @note:
* This function is necessary if you want to handle glyph layers by
* yourself. In particular, functions that operate with @FT_GlyphRec
* objects (like @FT_Get_Glyph or @FT_Glyph_To_Bitmap) don't have access
* to this information.
*

* How vectorial outlines are converted into bitmaps and pixmaps.
*
* @description:
* This section contains technical definitions.
* A raster or a rasterizer is a scan converter in charge of producing a
* pixel coverage bitmap that can be used as an alpha channel when
* compositing a glyph with a background. FreeType comes with two
* rasterizers: bilevel `raster1` and anti-aliased `smooth` are two
* separate modules. They are usually called from the high-level
* @FT_Load_Glyph or @FT_Render_Glyph functions and produce the entire
* coverage bitmap at once, while staying largely invisible to users.
*
* Instead of working with complete coverage bitmaps, it is also possible
* to intercept consecutive pixel runs on the same scanline with the same
* coverage, called _spans_, and process them individually. Only the
* `smooth` rasterizer permits this when calling @FT_Outline_Render with
* @FT_Raster_Params as described below.
*
* Working with either complete bitmaps or spans it is important to think
* of them as colorless coverage objects suitable as alpha channels to
