JDK-4417287 - JScrollPane violates Swing single thread rule
Description
MetalBumps creates a Frame and a Canvas in order to create the Image which will be blitted.  This could be reworked to be done with image producer/consumer.  This would likely improve startup time (as an extra Frame wouldn't have to be created).

Beyond the performance considerations this Frame has caused a world of strange behavior over the past few months including deadlocks with other parts of the JDK.  It is time for it to die.

EVALUATION See the description steve.wilson@eng 1998-10-28 This bug is SOOOO old. The right thing to do with this now is to use VolitileImage. Amy and I talked about this today. I'm going to reassign the bug to her. steve.wilson@Eng 2000-09-06 In talking with Chet he recommended to use Component.createImage, otherwise you can end up with an Image with the wrong GraphicsConfiguration. I've converted this class over to BufferedImage as a result of 4417287, refer to it for the details. scott.violet@eng 2001-06-25
