Markus Sauermann b1d6b34662 Always update Viewport's last_mosue_position
When the mouse cursor is over a embedded Window, the Viewport's
last_mouse_position did not get updated.
This patch makes sure that the update happens on every InputEventMouse.

Document canvas layer of embedded Windows.

Canvas drawing layer.
</brief_description>
<description>
Canvas drawing layer. [CanvasItem] nodes that are direct or indirect children of a [CanvasLayer] will be drawn in that layer. The layer is a numeric index that defines the draw order. The default 2D scene renders with index 0, so a [CanvasLayer] with index -1 will be drawn below, and one with index 1 will be drawn above. This is very useful for HUDs (in layer 1+ or above), or backgrounds (in layer -1 or below).
Embedded [Window]s are placed in layer 1024. CanvasItems in layer 1025 or above appear in front of embedded windows, CanvasItems in layer 1023 or below appear behind embedded windows.

<methods>
<method name="get_canvas" qualifiers="const">
<return type="RID" />
<description>
Returns the RID of the canvas used by this layer.
</description>
</method>
<method name="hide">
<return type="void" />
<description>
Hides any [CanvasItem] under this [CanvasLayer]. This is equivalent to setting [member visible] to [code]false[/code].
</description>
</method>
<method name="show">
<return type="void" />
<description>
Shows any [CanvasItem] under this [CanvasLayer]. This is equivalent to setting [member visible] to [code]true[/code].

</methods>
<members>
<member name="custom_viewport" type="Node" setter="set_custom_viewport" getter="get_custom_viewport">
The custom [Viewport] node assigned to the [CanvasLayer]. If [code]null[/code], uses the default viewport instead.
</member>
<member name="follow_viewport_enabled" type="bool" setter="set_follow_viewport" getter="is_following_viewport" default="false">
If enabled, the [CanvasLayer] will use the viewport's transform, so it will move when camera moves instead of being anchored in a fixed position on the screen.
Together with [member follow_viewport_scale] it can be used for a pseudo 3D effect.
</member>
<member name="follow_viewport_scale" type="float" setter="set_follow_viewport_scale" getter="get_follow_viewport_scale" default="1.0">
Scales the layer when using [member follow_viewport_enabled]. Layers moving into the foreground should have increasing scales, while layers moving into the background should have decreasing scales.
</member>
<member name="layer" type="int" setter="set_layer" getter="get_layer" default="1">
Layer index for draw order. Lower values are drawn first.
</member>
<member name="offset" type="Vector2" setter="set_offset" getter="get_offset" default="Vector2(0, 0)">
The layer's base offset.
</member>
<member name="rotation" type="float" setter="set_rotation" getter="get_rotation" default="0.0">
The layer's rotation in radians.
</member>
<member name="scale" type="Vector2" setter="set_scale" getter="get_scale" default="Vector2(1, 1)">
The layer's scale.
</member>
<member name="transform" type="Transform2D" setter="set_transform" getter="get_transform" default="Transform2D(1, 0, 0, 1, 0, 0)">
The layer's transform.
</member>
<member name="visible" type="bool" setter="set_visible" getter="is_visible" default="true">
If [code]false[/code], any [CanvasItem] under this [CanvasLayer] will be hidden.
Unlike [member CanvasItem.visible], visibility of a [CanvasLayer] isn't propagated to underlying layers.
</member>
