In Qt, can I QWebFrame::print() supply additional rendering layers?

wpf and win32 overlapping issue

What is the point of heightmaps?

But every engine I've seen loads height data from heightmaps... grayscale bitmaps. I just can't understand how this is useful - each point in a heightmap can have one of 256 values. But w...

I've been experimenting with Grails for the past two days and, so far, I'm really happy with it. Coming from Rails, the only thing I've really been missing here is the dev-mode debug information shown after the page has been served.
