Metrics & operator= (const Metrics & other)bool operator== (const Metrics & other)bool operator!= (const Metrics & other)float scale_x ()The ratio between the size of one logical pixel within the node's local
coordinate system and the size of one physical pixel of the rendering
target.
This scale factors change in relation to the resolution of the rendering
target and the scale transformations applied by containing nodes.
They are always strictly positive and non-zero.
For example, suppose the rendering target is a high resolution display
with a device pixel ratio of 2.0 meaning that each logical pixel
within the model corresponds to two physical pixels of the display.
Assuming no scale transformations affect the node, then its metrics event
will report a scale factor of 2.0.
Building on this example, if instead the node's parent applies a
scale transformation of 0.25 to the node, then the node's metrics event
will report a scale factor of 0.5 indicating that the node should render
its content at a reduced resolution and level of detail since a smaller
area of physical pixels (half the size in each dimension) will be rendered.
