	<brief_description>
		A variation of a font with additional settings.
	</brief_description>
	<description>
		Provides OpenType variations, simulated bold / slant, and additional font settings like OpenType features and extra spacing.
		To use simulated bold font variant:
		[codeblocks]
		[gdscript]
		var fv = FontVariation.new()
		fv.base_font = load("res://BarlowCondensed-Regular.ttf")
		fv.variation_embolden = 1.2
		$Label.add_theme_font_override("font", fv)
		$Label.add_theme_font_size_override("font_size", 64)
		[/gdscript]
		[csharp]
		var fv = new FontVariation();
		fv.SetBaseFont(ResourceLoader.Load&lt;FontFile&gt;("res://BarlowCondensed-Regular.ttf"));
		fv.SetVariationEmbolden(1.2);
		GetNode("Label").AddThemeFontOverride("font", fv);
		GetNode("Label").AddThemeFontSizeOverride("font_size", 64);
		[/csharp]
		[/codeblocks]
		To set the coordinate of multiple variation axes:
		[codeblock]
		var fv = FontVariation.new();
		var ts = TextServerManager.get_primary_interface()
		fv.base_font = load("res://BarlowCondensed-Regular.ttf")
		fv.variation_opentype = { ts.name_to_tag("wght"): 900, ts.name_to_tag("custom_hght"): 900 }
		[/codeblock]

		<member name="base_font" type="Font" setter="set_base_font" getter="get_base_font">
			Base font used to create a variation. If not set, default [Theme] font is used.

			Extra baseline offset (as a fraction of font height).

		<member name="variation_embolden" type="float" setter="set_variation_embolden" getter="get_variation_embolden" default="0.0">
			If is not equal to zero, emboldens the font outlines. Negative values reduce the outline thickness.
			[b]Note:[/b] Emboldened fonts might have self-intersecting outlines, which will prevent MSDF fonts and [TextMesh] from working correctly.
		</member>
		<member name="variation_face_index" type="int" setter="set_variation_face_index" getter="get_variation_face_index" default="0">
			Active face index in the TrueType / OpenType collection file.
		</member>

			Font OpenType variation coordinates. More info: [url=https://docs.microsoft.com/en-us/typography/opentype/spec/dvaraxisreg]OpenType variation tags[/url].
			[b]Note:[/b] This [Dictionary] uses OpenType tags as keys. Variation axes can be identified both by tags ([int], e.g. [code]0x77678674[/code]) and names ([String], e.g. [code]wght[/code]). Some axes might be accessible by multiple names. For example, [code]wght[/code] refers to the same axis as [code]weight[/code]. Tags on the other hand are unique. To convert between names and tags, use [method TextServer.name_to_tag] and [method TextServer.tag_to_name].
			[b]Note:[/b] To get available variation axes of a font, use [method Font.get_supported_variation_list].

		<member name="variation_transform" type="Transform2D" setter="set_variation_transform" getter="get_variation_transform" default="Transform2D(1, 0, 0, 1, 0, 0)">
			2D transform, applied to the font outlines, can be used for slanting, flipping and rotating glyphs.
			For example, to simulate italic typeface by slanting, apply the following transform [code]Transform2D(1.0, slant, 0.0, 1.0, 0.0, 0.0)[/code].
