Phew! I've added the beginning of support for histograms to Krita tonight. A 
nice KisHistogram class to compute the stuff (done, apart from median, stddev 
and percentile, which I haven't got a clue about), a widget and a plugin. 
What I still need to do is create the bar chart pixmap and the gradient 
pixmap, but the rest is mostly done. 

Does anyone have, by accident, some nice barchart and/or gradient code lying 
about? I really hate painting charts by hand....

Oh, and this code uses Cyrille's iterators. Pretty speedy, but I am convinced 
I want to iterate by pixel. I also discovered that our color strategies have 
a nice function to return the channels they handle, and their ordering. Now 
we only need to add types, and package the channels in a vector, not just a 
chunk of memory with a pointer pointing towards them.
