 TextEncoding determines whether text specifies character codes and their encoded
 size, or glyph indices. Characters are encoded as specified by the
 #A Unicode standard # https://unicode.org/standard/standard.html ##
 .

 Character codes encoded size are specified by UTF-8, UTF-16, or UTF-32.
 All character code formats are able to represent all of Unicode, differing only
 in the total storage required.

 #A UTF-8 (RFC 3629) # https://tools.ietf.org/html/rfc3629 ##
 encodes each character as one or more 8-bit bytes.

 #A UTF-16 (RFC 2781) # https://tools.ietf.org/html/rfc2781 ##
 encodes each character as one or two 16-bit words.

 #A UTF-32 # https://www.unicode.org/versions/Unicode5.0.0/ch03.pdf ##
 encodes each character as one 32-bit word.

 Font_Manager uses font data to convert character code points into glyph indices.
 A glyph index is a 16-bit word.
 #Enum SkTextEncoding ##
 #Topic Text_Encoding ##

 #Topic Font_Hinting
 #Line # glyph outline adjustment ##
 #EnumClass SkFontHinting
 #Const kNone 0
 #Line # glyph outlines unchanged ##
     Leaves glyph outlines unchanged from their native representation.
     With FreeType, this is equivalent to the FT_LOAD_NO_HINTING
     bit-field constant supplied to FT_Load_Glyph, which indicates that the vector
     outline being loaded should not be fitted to the pixel grid but simply scaled
     to 26.6 fractional pixels.
 ##
 #Const kSlight 1
 #Line # minimal modification to improve contrast ##
     Modifies glyph outlines minimally to improve contrast.
     With FreeType, this is equivalent in spirit to the
     FT_LOAD_TARGET_LIGHT value supplied to FT_Load_Glyph. It chooses a
     lighter hinting algorithm for non-monochrome modes.
     Generated Glyphs may be fuzzy but better resemble their original shape.
 ##
 #Const kNormal 2
 #Line # glyph outlines modified to improve contrast ##
     Modifies glyph outlines to improve contrast. This is the default.
     With FreeType, this supplies FT_LOAD_TARGET_NORMAL to FT_Load_Glyph,
     choosing the default hinting algorithm, which is optimized for standard
     gray-level rendering.
 ##
 #Const kFull 3
 #Line # modifies glyph outlines for maximum contrast ##
     Modifies glyph outlines for maximum contrast. With FreeType, this selects
     FT_LOAD_TARGET_LCD or FT_LOAD_TARGET_LCD_V if kLCDRenderText_Flag is set.
     FT_LOAD_TARGET_LCD is a variant of FT_LOAD_TARGET_NORMAL optimized for
     horizontally decimated LCD displays; FT_LOAD_TARGET_LCD_V is a
     variant of FT_LOAD_TARGET_NORMAL optimized for vertically decimated LCD displays.

 #Topic Font_Metrics
 #Struct SkFontMetrics
 #Line # values computed by Font_Manager using Typeface ##

     SkFontMetrics is filled out by SkPaint::getFontMetrics. SkFontMetrics contents
     reflect the values
     computed by Font_Manager using Typeface. Values are set to zero if they are
     not available.

     All vertical values are relative to the baseline, on a y-axis pointing down.
     Zero is on the baseline, negative values are above the baseline, and positive
     values are below the baseline.

     fUnderlineThickness and fUnderlinePosition have a bit set in fFlags if their values
     are valid, since their value may be zero.

     fStrikeoutThickness and fStrikeoutPosition have a bit set in fFlags if their values
     are valid, since their value may be zero.

     #Enum FontMetricsFlags
     #Line # valid Font_Metrics ##

     FontMetricsFlags are set in fFlags when underline and strikeout metrics are valid;
     the underline or strikeout metric may be valid and zero.
     Fonts with embedded bitmaps may not have valid underline or strikeout metrics.

     #Member SkScalar    fUnderlinePosition
     #Line # underline position relative to baseline ##
        Position of the top of the underline stroke relative to the baseline.
        Typically positive when valid.

        If the metric is valid, the kUnderlinePositionIsValid_Flag is set in fFlags.
        If kUnderlinePositionIsValid_Flag is clear, fUnderlinePosition is zero.
     ##

     #Member SkScalar    fStrikeoutThickness
     #Line # strikeout thickness ##

         If the metric is valid, the kStrikeoutThicknessIsValid_Flag is set in fFlags.

     ##

     #Member SkScalar    fStrikeoutPosition
     #Line # strikeout position relative to baseline ##
         Position of the bottom of the strikeout stroke relative to the baseline.

	TextEncoding determines whether text specifies character codes and their encoded
	size, or glyph indices. Characters are encoded as specified by the
	#A Unicode standard # https://unicode.org/standard/standard.html ##
	.

	Character codes encoded size are specified by UTF-8, UTF-16, or UTF-32.
	All character code formats are able to represent all of Unicode, differing only
	in the total storage required.

	#A UTF-8 (RFC 3629) # https://tools.ietf.org/html/rfc3629 ##
	encodes each character as one or more 8-bit bytes.

	#A UTF-16 (RFC 2781) # https://tools.ietf.org/html/rfc2781 ##
	encodes each character as one or two 16-bit words.

	#A UTF-32 # https://www.unicode.org/versions/Unicode5.0.0/ch03.pdf ##
	encodes each character as one 32-bit word.

	Font_Manager uses font data to convert character code points into glyph indices.
	A glyph index is a 16-bit word.

	#Topic Text_Encoding ##

	#Topic Font_Hinting
	#Line # glyph outline adjustment ##
	#EnumClass SkFontHinting
	#Const kNone 0
	#Line # glyph outlines unchanged ##
	Leaves glyph outlines unchanged from their native representation.
	With FreeType, this is equivalent to the FT_LOAD_NO_HINTING
	bit-field constant supplied to FT_Load_Glyph, which indicates that the vector
	outline being loaded should not be fitted to the pixel grid but simply scaled
	to 26.6 fractional pixels.
	##
	#Const kSlight 1
	#Line # minimal modification to improve contrast ##
	Modifies glyph outlines minimally to improve contrast.
	With FreeType, this is equivalent in spirit to the
	FT_LOAD_TARGET_LIGHT value supplied to FT_Load_Glyph. It chooses a
	lighter hinting algorithm for non-monochrome modes.
	Generated Glyphs may be fuzzy but better resemble their original shape.
	##
	#Const kNormal 2
	#Line # glyph outlines modified to improve contrast ##
	Modifies glyph outlines to improve contrast. This is the default.
	With FreeType, this supplies FT_LOAD_TARGET_NORMAL to FT_Load_Glyph,
	choosing the default hinting algorithm, which is optimized for standard
	gray-level rendering.
	##
	#Const kFull 3
	#Line # modifies glyph outlines for maximum contrast ##
	Modifies glyph outlines for maximum contrast. With FreeType, this selects
	FT_LOAD_TARGET_LCD or FT_LOAD_TARGET_LCD_V if kLCDRenderText_Flag is set.
	FT_LOAD_TARGET_LCD is a variant of FT_LOAD_TARGET_NORMAL optimized for
	horizontally decimated LCD displays; FT_LOAD_TARGET_LCD_V is a
	variant of FT_LOAD_TARGET_NORMAL optimized for vertically decimated LCD displays.

	SkFontMetrics is filled out by SkPaint::getFontMetrics. SkFontMetrics contents
	reflect the values
	computed by Font_Manager using Typeface. Values are set to zero if they are
	not available.

	All vertical values are relative to the baseline, on a y-axis pointing down.
	Zero is on the baseline, negative values are above the baseline, and positive
	values are below the baseline.

	fUnderlineThickness and fUnderlinePosition have a bit set in fFlags if their values
	are valid, since their value may be zero.

	fStrikeoutThickness and fStrikeoutPosition have a bit set in fFlags if their values
	are valid, since their value may be zero.

	#Enum FontMetricsFlags
	#Line # valid Font_Metrics ##

	FontMetricsFlags are set in fFlags when underline and strikeout metrics are valid;
	the underline or strikeout metric may be valid and zero.
	Fonts with embedded bitmaps may not have valid underline or strikeout metrics.
