Implement built-in classes Vector4, Vector4i and Projection. * Two versions of Vector4 (float and integer). * A Projection class, which is a 4x4 matrix specialized in projection types. These types have been requested for a long time, but given they were very corner case they were not added before. Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity. **Q**: Why Projection and not Matrix4? **A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming.

|
Label displays plain text on the screen. It gives you control over the horizontal and vertical alignment and can wrap the text inside the node's bounding rectangle. It doesn't support bold, italics, or other formatting. For that, use [RichTextLabel] instead.
|
|
[b]Note:[/b] Contrarily to most other [Control]s, Label's [member Control.mouse_filter] defaults to [constant Control.MOUSE_FILTER_IGNORE] (i.e. it doesn't react to mouse input events). This implies that a label won't display any configured [member Control.hint_tooltip], unless you change its mouse filter.

<member name="autowrap_mode" type="int" setter="set_autowrap_mode" getter="get_autowrap_mode" enum="TextServer.AutowrapMode" default="0">
|
|
If set to something other than [constant TextServer.AUTOWRAP_OFF], the text gets wrapped inside the node's bounding rectangle. If you resize the node, it will change its height automatically to show all the text. To see how each mode behaves, see [enum TextServer.AutowrapMode].
