don't do this. a size allocate will always be followed by an expose
event. all drawing must be done from the expose event handler, always.
just store the width and height in the size allocate handler for later
use. if for some reason, the expose event is really missing, use
gtk_widget_queue_draw() to cause one to occur "soon".
