	<brief_description>
		Texture for 2D and 3D.
	</brief_description>
	<description>
		A texture works by registering an image in the video hardware, which then can be used in 3D models or 2D [Sprite2D] or GUI [Control].
		Textures are often created by loading them from a file. See [method @GDScript.load].
		[Texture2D] is a base for other resources. It cannot be used directly.
		[b]Note:[/b] The maximum texture size is 16384×16384 pixels due to graphics hardware limitations. Larger textures may fail to import.

		<method name="_draw" qualifiers="virtual const">
			<return type="void" />
			<param index="0" name="to_canvas_item" type="RID" />
			<param index="1" name="pos" type="Vector2" />
			<param index="2" name="modulate" type="Color" />
			<param index="3" name="transpose" type="bool" />
			<description>
				Called when the entire [Texture2D] is requested to be drawn over a [CanvasItem], with the top-left offset specified in [param pos]. [param modulate] specifies a multiplier for the colors being drawn, while [param transpose] specifies whether drawing should be performed in column-major order instead of row-major order (resulting in 90-degree clockwise rotation).
				[b]Note:[/b] This is only used in 2D rendering, not 3D.

			<description>
				Called when the [Texture2D] is requested to be drawn onto [CanvasItem]'s specified [param rect]. [param modulate] specifies a multiplier for the colors being drawn, while [param transpose] specifies whether drawing should be performed in column-major order instead of row-major order (resulting in 90-degree clockwise rotation).

			<description>
				Called when a part of the [Texture2D] specified by [param src_rect]'s coordinates is requested to be drawn onto [CanvasItem]'s specified [param rect]. [param modulate] specifies a multiplier for the colors being drawn, while [param transpose] specifies whether drawing should be performed in column-major order instead of row-major order (resulting in 90-degree clockwise rotation).
