A GdkPixmap is on the X server (it represents a Pixmap, which
is an XID).

Effectivly, gdk_draw_pixbuf() is a server upload, yes.

You are better off to create a GdkPixmap from your GdkPixbuf,
free your GdkPixbuf and use gdk_draw_drawable() for exposes.

Writing such a document is definitly out of scope for an API reference
(i.e., using a GtkDrawingArea is not using its API)

If you are going to write a GtkDrawingArea, you probably know what you
are doing and you know how to derive, implement and write your own widgets.
