			[b]Note:[/b] This only applies if [member alpha_cut] is set to [constant ALPHA_CUT_DISABLED] (default value).
			[b]Note:[/b] This only applies to sorting of transparent objects. This will not impact how transparent objects are sorted relative to opaque objects. This is because opaque objects are not sorted, while transparent objects are sorted from back to front (subject to priority).

	<constants>
		<constant name="FLAG_SHADED" value="0" enum="DrawFlags">
			If set, lights in the environment affect the label.
		</constant>
		<constant name="FLAG_DOUBLE_SIDED" value="1" enum="DrawFlags">
			If set, text can be seen from the back as well. If not, the text is invisible when looking at it from behind.
		</constant>
		<constant name="FLAG_DISABLE_DEPTH_TEST" value="2" enum="DrawFlags">
			Disables the depth test, so this object is drawn on top of all others. However, objects drawn after it in the draw order may cover it.
		</constant>
		<constant name="FLAG_FIXED_SIZE" value="3" enum="DrawFlags">
			Label is scaled by depth so that it always appears the same size on screen.
		</constant>
		<constant name="FLAG_MAX" value="4" enum="DrawFlags">
			Represents the size of the [enum DrawFlags] enum.
		</constant>
		<constant name="ALPHA_CUT_DISABLED" value="0" enum="AlphaCutMode">
			This mode performs standard alpha blending. It can display translucent areas, but transparency sorting issues may be visible when multiple transparent materials are overlapping.
		</constant>
		<constant name="ALPHA_CUT_DISCARD" value="1" enum="AlphaCutMode">
			This mode only allows fully transparent or fully opaque pixels. This mode is also known as [i]alpha testing[/i] or [i]1-bit transparency[/i].
			[b]Note:[/b] This mode might have issues with anti-aliased fonts and outlines, try adjusting [member alpha_scissor_threshold] or using SDF font.
			[b]Note:[/b] When using text with overlapping glyphs (e.g., cursive scripts), this mode might have transparency sorting issues between the main text and the outline.
		</constant>
		<constant name="ALPHA_CUT_OPAQUE_PREPASS" value="2" enum="AlphaCutMode">
			This mode draws fully opaque pixels in the depth prepass. This is slower than [constant ALPHA_CUT_DISABLED] or [constant ALPHA_CUT_DISCARD], but it allows displaying translucent areas and smooth edges while using proper sorting.
			[b]Note:[/b] When using text with overlapping glyphs (e.g., cursive scripts), this mode might have transparency sorting issues between the main text and the outline.
		</constant>

		<constant name="ALIGN_RIGHT" value="2" enum="Align">
			Align rows to the right.

			Align the whole text to the top.
		</constant>
		<constant name="VALIGN_CENTER" value="1" enum="VAlign">
			Align the whole text to the center.
