XML/Dimension

<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>

• x - Horizontal distance affected by UI scaling; (+) right and (-) left.
• y - Vertical distance affected by UI scaling; (+) up and (-) down.

<AbsDimension> defines coordinates in scaling-dependent units (same as <Dimension>). <RelDimension> defines coordinates relative to the entire screen, where 0 and 1 are the edges.

• x - Horizontal distance affected by UI scaling; (+) right and (-) left.
• y - Vertical distance affected by UI scaling; (+) up and (-) down.
• x - Ratio of screen width, from left to right edges.
• y - Ratio of screen height, from bottom to top edges.

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.

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