Doctool: Remove version attribute from XML header
We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).

<brief_description>
A node used to add local fog with the volumetric fog effect.
</brief_description>
<description>
[FogVolume]s are used to add localized fog into the global volumetric fog effect. [FogVolume]s can also remove volumetric fog from specific areas if using a [FogMaterial] with a negative [member FogMaterial.density].
Performance of [FogVolume]s is directly related to their relative size on the screen and the complexity of their attached [FogMaterial]. It is best to keep [FogVolume]s relatively small and simple where possible.
[b]Note:[/b] [FogVolume]s only have a visible effect if [member Environment.volumetric_fog_enabled] is [code]true[/code]. If you don't want fog to be globally visible (but only within [FogVolume] nodes), set [member Environment.volumetric_fog_density] to [code]0.0[/code].

<member name="material" type="Material" setter="set_material" getter="get_material">
The [Material] used by the [FogVolume]. Can be either a built-in [FogMaterial] or a custom [ShaderMaterial].
</member>
<member name="shape" type="int" setter="set_shape" getter="get_shape" enum="RenderingServer.FogVolumeShape" default="3">
The shape of the [FogVolume]. This can be set to either [constant RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID], [constant RenderingServer.FOG_VOLUME_SHAPE_CONE], [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER], [constant RenderingServer.FOG_VOLUME_SHAPE_BOX] or [constant RenderingServer.FOG_VOLUME_SHAPE_WORLD].
</member>
<member name="size" type="Vector3" setter="set_size" getter="get_size" default="Vector3(2, 2, 2)">
The size of the [FogVolume] when [member shape] is [constant RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID], [constant RenderingServer.FOG_VOLUME_SHAPE_CONE], [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER] or [constant RenderingServer.FOG_VOLUME_SHAPE_BOX].
[b]Note:[/b] Thin fog volumes may appear to flicker when the camera moves or rotates. This can be alleviated by increasing [member ProjectSettings.rendering/environment/volumetric_fog/volume_depth] (at a performance cost) or by decreasing [member Environment.volumetric_fog_length] (at no performance cost, but at the cost of lower fog range). Alternatively, the [FogVolume] can be made thicker and use a lower density in the [member material].
[b]Note:[/b] If [member shape] is [constant RenderingServer.FOG_VOLUME_SHAPE_CONE] or [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER], the cone/cylinder will be adjusted to fit within the size. Non-uniform scaling of cone/cylinder shapes via the [member size] property is not supported, but you can scale the [FogVolume] node instead.
