* Currently, FreeType only supports bitmap glyphs in PNG format for this

*
* @note:

* @FT_PARAM_TAG_IGNORE_SBIX, an application can switch off 'sbix'
* handling so that the face is treated as an ordinary outline font with
* scalable outlines.
*
* Here is some pseudo code that roughly illustrates how to implement
* 'sbix' handling according to the OpenType specification.
*
* ```
* if ( FT_HAS_SBIX( face ) )
* {
* // open font as a scalable one without sbix handling
* FT_Face face2;

* FreeType has two rasterizers for generating SDF, namely:
*
* 1. `sdf` for generating SDF directly from glyph's outline, and
*
* 2. `bsdf` for generating SDF from rasterized bitmaps.
*
* Depending on the glyph type (i.e., outline or bitmap), one of the two
* rasterizers is chosen at runtime and used for generating SDFs. To
* force the use of `bsdf` you should render the glyph with any of the
* FreeType's other rendering modes (e.g., `FT_RENDER_MODE_NORMAL`) and
* then re-render with `FT_RENDER_MODE_SDF`.
*
* There are some issues with stability and possible failures of the SDF
* renderers (specifically `sdf`).
*
* 1. The `sdf` rasterizer is sensitive to really small features (e.g.,
* sharp turns that are less than 1~pixel) and imperfections in the
* glyph's outline, causing artifacts in the final output.
*
* 2. The `sdf` rasterizer has limited support for handling intersecting
* contours and *cannot* handle self-intersecting contours whatsoever.
* Self-intersection happens when a single connected contour intersect
* itself at some point; having these in your font definitely pose a
* problem to the rasterizer and cause artifacts, too.
*
* 3. Generating SDF for really small glyphs may result in undesirable
* output; the pixel grid (which stores distance information) becomes
* too coarse.
*
* 4. Since the output buffer is normalized, precision at smaller spreads
* is greater than precision at larger spread values because the
* output range of [0..255] gets mapped to a smaller SDF range. A
* spread of~2 should be sufficient in most cases.
*
* Points (1) and (2) can be avoided by using the `bsdf` rasterizer,

* 1. When `FT_Load_Glyph` needs to preset the glyph slot.
*
* 2. Right before the `svg` module calls the render callback hook.
*
* When it is the former, the argument `cache` is set to `FALSE`. When
* it is the latter, the argument `cache` is set to `TRUE`. This
* distinction has been made because many calculations that are necessary
* for presetting a glyph slot are the same needed later for the render
* callback hook. Thus, if `cache` is `TRUE`, the hook can _cache_ those
* calculations in a memory block referenced by the state pointer.
*
* This hook is expected to preset the slot by setting parameters such as
* `bitmap_left`, `bitmap_top`, `width`, `rows`, `pitch`, and
* `pixel_mode`. It is also expected to set all the metrics for the slot
* including the vertical advance if it is not already set. Typically,
* fonts have horizontal advances but not vertical ones. If those are
* available, they had already been set, otherwise they have to be
* estimated and set manually. The hook must take into account the
* transformations that have been set, and translate the transformation
* matrices into the SVG coordinate system, as the original matrix is
* intended for the TTF/CFF coordinate system.
