An image created with Component.createImage() is supposed to be filled with the
default component background gray.
Currently, it simply mallocs the pixmap data without initializing it, which is
also a mild security flaw.
Suggested fix is to do a fillRect() after creating the graphics context in
GtkComponentPeer.java.
An (faster) alternative would be to do a memset in the c method
Java_gnu_java_awt_peer_gtk_GdkGraphics_initState__II.
