[Interest] QTreeView expand/expandAll performance

[William Hallatt]

@William - there is no real noticeable difference between Debug and Release
modes and I haven't been able to extract anything of real use from the
profiler either (perhaps this is lack of experience on my part, I added a
screenshot of the the output here:

@Paul - I am using my own styled delegate, will have a look at that, thanks
for the idea!

@Marian - will have a look into these as well and revise data()

Thanks for all the pointers!
