Drawables and surfaces have been separated into different objects. First
you'll have to create a drawable then you'll have to create a surface
and the surface must then be attached to a portion of the drawable to
make rendering operations on the surface target the drawable.

When attaching the surface to the drawable, make sure you're attaching
it to the correct buffer. You probably want to attach it to the back
buffer if the drawable is double buffered.
