Speed: animations with SWT [message #438676]

Hi!

SWT/Swing is de facto unusable slow when it comes to image processing
for a matter of int array->Image convertion.

How does SWT perform in this case? At a glance I'd need to create a new
Image instance each time I change the buffer and I cannot recycle it:
new Image(dev, imageData.setPixels(...));

Can this be fast? I do not have a fixed number of frames (e.g. GIF
animation) but it's a real-time rendering effect.

Write a simple example/benchmark and someone here will look into it.
