target surface for the context
a newly allocated #cairo_t with a reference count of 1. The initial reference count should be released with cairo.global.destroy when you are done using the #cairo_t. This function never returns null. If memory cannot be allocated, a special #cairo_t object will be returned on which cairo.context.Context.status returns cairo.types.Status.NoMemory. If you attempt to target a surface which does not support writing (such as #cairo_mime_surface_t) then a cairo.types.Status.WriteError will be raised. You can use this object normally, but no drawing will be done.
Creates a new #cairo_t with all graphics state parameters set to default values and with target as a target surface. The target surface should be constructed with a backend-specific function such as cairo.global.imageSurfaceCreate (or any other <function>cairo_<emphasis>backend</emphasis>_surface_create(<!-- -->)</function> variant).
This function references target, so you can immediately call cairo.surface.Surface.destroy on it if you don't need to maintain a separate reference to it.
