Is the gtkdrawingarea a server or client side widget?

[Erik Jonsson <gtk nesqi se>]

If I create a GtkDrawingArea and only use GdkPixMaps to
update it. Will all graphics be handled on the server side?

If the DrawingArea uses only a GdkScreen I guess it should
all be server side but if it's using a GdkPixBuf or GdkRBG
internaly it might have to copy data from the client every
update. Right?

By the way... Is there a good reason for the GdkDrawingArea 
not to have documentation?
