* gnu/java/awt/ClasspathToolkit.java
(getScreenSize, getColorModel, getFontMetrics, getImage, createImage,
createImageProducer, registerImageIOSpis):
Remove redundant (overloaded) methods.
* gnu/java/awt/peer/gtk/GtkToolkit.java
(registerImageIOSpis): Move registration to static initializer.
* javax/imageio/spi/IIORegistry.java:
Remove call to Toolkit registration method.
