This introduces a system property in XGraphics2D, which turns on opaque
image rendering for all images, even translucent ones. This is intended
for debugging and demostration purposes only.
2008-02-18 Roman Kennke <[EMAIL PROTECTED]>
* gnu/java/awt/peer/x/XGraphics2D.java
(RENDER_OPAQUE): New constant with system property to
turn on opaque image rendering.
(rawDrawImage): Render images opaque when system property
is set. This is for demonstration and debugging purposes only.
