<Dimension> defines a dimension (size, offset, etc.) as x and y, or with a child element to specify the coordinate system.

```<Dimension x="" y="">
<AbsDimension x="" y="" />
<RelDimension x="" y="" />
</Dimension>
```

## Attributes

x (xs:int?) - Horizontal distance in scaling-dependent units; (+) right and (-) left.
y (xs:int?) - Vertical distance in scaling-dependent units; (+) up and (-) down.

## Child elements

<AbsDimension> defines coordinates in scaling-dependent units (same as <Dimension>).

x (xs:int) - Horizontal distance in scaling-dependent units; (+) right and (-) left.
y (xs:int) - Vertical distance in scaling-dependent units; (+) up and (-) down.

<RelDimension> defines coordinates relative to the entire screen, where 0 and 1 are the edges.

x (xs:float) - Ratio of screen width, from left to right edges.
y (xs:float) - Ratio of screen height, from bottom to top edges.

## Example

Creates a parent frame that fills one quarter of the screen, and a child frame that is set to 200x100 units and is 22 units from the top edge of its parent.

```<Frame name="MyFrame">
<Size>
<RelDimension x="0.5" y="0.5"/>
</Size>
<Frames>
<Frame name="\$parentChild">
<Size x="200" y="100"/>
<Anchors>
<Anchor point="TOP">
<Offset>
<AbsDimension x="0" y="-22" />
</Offset>
</Anchor>
</Anchors>
</Frame>
</Frames>
</Frame>
```

N.B.: <Anchor> also has its own x and y attributes, so this could be written in fewer lines without <Offset> and <AbsDimension>.
