Hello all,

All is in the tile, is QImage::copy threadsafe? The method is const but 
is it enough? Documentation does not state it is thread safe so I am 

My case is I have a QImage loaded in the main thread, and many many 
threads that keep extracting small rectangles from it using 
QImage::copy. No other operations occur on the QImage once loaded.

Is it safe?
