int sdlGetNumberProperty(int props, String? name, int defaultValue)

Get a number property from a group of properties.

You can use SDL_GetPropertyType() to query whether the property exists and is a number property.

\param props the properties to query. \param name the name of the property to query. \param default_value the default value of the property. \returns the value of the property, or default_value if it is not set or not a number property.
