+		Singleton for window management functions.
 	</brief_description>
 	<description>
+		[DisplayServer] handles everything related to window management. This is separated from [OS] as a single operating system may support multiple display servers.
+		[b]Headless mode:[/b] Starting the engine with the [code]--headless[/code] [url=$DOCS_URL/tutorials/editor/command_line_tutorial.html]command line argument[/url] disables all rendering and window management functions. Most functions from [DisplayServer] will return dummy values in this case.

-		Godot can record videos with non-real-time simulation. Like the [code]--fixed-fps[/code] command line argument, this forces the reported [code]delta[/code] in [method Node._process] functions to be identical across frames, regardless of how long it actually took to render the frame. This can be used to record high-quality videos with perfect frame pacing regardless of your hardware's capabilities.

This can be used to record high-quality videos with perfect frame pacing regardless of your hardware's capabilities.
 		Godot has 2 built-in [MovieWriter]s:
 		- AVI container with MJPEG for video and uncompressed audio ([code].avi[/code] file extension). Lossy compression, medium file sizes, fast encoding. The lossy compression quality can be adjusted by changing [member ProjectSettings.editor/movie_writer/mjpeg_quality]. The resulting file can be viewed in most video players, but it must be converted to another format for viewing on the web or by Godot with [VideoStreamPlayer]. MJPEG does not support transparency. AVI output is currently limited to a file of 4 GB in size at most.
 		- PNG image sequence for video and WAV for audio ([code].png[/code] file extension). Lossless compression, large file sizes, slow encoding. Designed to be encoded to a video file with another tool such as [url=https://ffmpeg.org/]FFmpeg[/url] after recording. Transparency is currently not supported, even if the root viewport is set to be transparent.

 		Similarly, in 2D, a canvas is needed to draw all canvas items.
 		In 3D, all visible objects are comprised of a resource and an instance. A resource can be a mesh, a particle system, a light, or any other 3D object. In order to be visible resources must be attached to an instance using [method instance_set_base]. The instance must also be attached to the scenario using [method instance_set_scenario] in order to be visible.
 		In 2D, all visible objects are some form of canvas item. In order to be visible, a canvas item needs to be the child of a canvas attached to a viewport, or it needs to be the child of another canvas item that is eventually attached to the canvas.
