Interface WpViewporterRequests

public interface WpViewporterRequests

surface cropping and scaling

The global interface exposing surface cropping and scaling capabilities is used to instantiate an interface extension for a wl_surface object. This extended interface will then allow cropping and scaling the surface contents, effectively disconnecting the direct relationship between the buffer and the surface size.
