// cx (Extent Length)
// Specifies the length of the extents rectangle in EMUs. This rectangle shall dictate the size of the object as displayed (the result of any scaling to the original object).
// Example: Consider a DrawingML object specified as follows:
// <… cx="1828800" cy="200000"/>
// The cx attributes specifies that this object has a height of 1828800 EMUs (English Metric Units). end example]
// The possible values for this attribute are defined by the ST_PositiveCoordinate simple type (§20.1.10.42).
// cy (Extent Width)
// Specifies the width of the extents rectangle in EMUs. This rectangle shall dictate the size of the object as displayed (the result of any scaling to the original object).
// Example: Consider a DrawingML object specified as follows:
// < … cx="1828800" cy="200000"/>
