		DynamicFont renders vector font files at runtime.
	</brief_description>
	<description>
		DynamicFont renders vector font files dynamically at runtime instead of using a prerendered texture atlas like [BitmapFont]. This trades the faster loading time of [BitmapFont]s for the ability to change font parameters like size and spacing during runtime. [DynamicFontData] is used for referencing the font file paths. DynamicFont also supports defining one or more fallback fonts, which will be used when displaying a character not supported by the main font.
		DynamicFont uses the [url=https://www.freetype.org/]FreeType[/url] library for rasterization. Supported formats are TrueType ([code].ttf[/code]), OpenType ([code].otf[/code]), Web Open Font Format 1 ([code].woff[/code]), and  Web Open Font Format 2 ([code].woff2[/code]).
		[codeblock]
		var dynamic_font = DynamicFont.new()
		dynamic_font.font_data = load("res://BarlowCondensed-Bold.ttf")
		dynamic_font.size = 64
		$"Label".set("custom_fonts/font", dynamic_font)
		[/codeblock]
		[b]Note:[/b] DynamicFont doesn't support features such as kerning, right-to-left typesetting, ligatures, text shaping, variable fonts and optional font features yet. If you wish to "bake" an optional font feature into a TTF font file, you can use [url=https://fontforge.org/]FontForge[/url] to do so. In FontForge, use [b]File &gt; Generate Fonts[/b], click [b]Options[/b], choose the desired features then generate the font.

	<members>
		<member name="extra_spacing_bottom" type="int" setter="set_spacing" getter="get_spacing" default="0">
			Extra spacing at the bottom in pixels.

		<member name="extra_spacing_char" type="int" setter="set_spacing" getter="get_spacing" default="0">
			Extra spacing for each character in pixels.
			This can be a negative number to make the distance between characters smaller.

			Extra spacing for the space character (in addition to [member extra_spacing_char]) in pixels.
			This can be a negative number to make the distance between words smaller.

			The font outline's color.
			[b]Note:[/b] It's recommended to leave this at the default value so that you can adjust it in individual controls. For example, if the outline is made black here, it won't be possible to change its color using a Label's font outline modulate theme item.

		<member name="outline_size" type="int" setter="set_outline_size" getter="get_outline_size" default="0">
			The font outline's thickness in pixels (not relative to the font size).

			The font size in pixels.
		</member>
		<member name="use_filter" type="bool" setter="set_use_filter" getter="get_use_filter" default="false">
			If [code]true[/code], filtering is used. This makes the font blurry instead of pixelated when scaling it if font oversampling is disabled or ineffective. It's recommended to enable this when using the font in a control whose size changes over time, unless a pixel art aesthetic is desired.
		</member>
		<member name="use_mipmaps" type="bool" setter="set_use_mipmaps" getter="get_use_mipmaps" default="false">
			If [code]true[/code], mipmapping is used. This improves the font's appearance when downscaling it if font oversampling is disabled or ineffective.
