Subject: [Bug AWT/18312] New: Component.createImage() doesn't clear bitmap
X-Bugzilla-Reason: CC
X-SW-Source: 2004-11/txt/msg00594.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

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.
