An object that you use to configure new rasterization rate maps.
Mac Catalyst 13.4+Beta
To create a new rate map, first create a MTLRasterizationRateMapDescriptor object and set its property values. Then, call the newRasterizationRateMapWithScreenSize:layerCount:layers: method of a MTLDevice object to create the rate map.
When you create a rate map, Metal copies property values from the descriptor into it. You can reuse a MTLRasterizationRateMapDescriptor object, modifying its property values as needed, without affecting the rate maps you already created.
A compiled read-only object that determines how to apply variable rasterization rates when rendering.
