I thought that glitz_surface_create call makes the
whole job (as it gets drawable as argument). I could
not guess that glitz_surface_attach is needed too.
On this occasion, can you recommend the correct
procedure for resizing of surfaces and/or drawables?
Their constructors accept width and height parameters,
but what if I want to resize an existing surface?
