graphicsview: use std::sort instead of qSort
In almost all cases, std::sort is wildly faster than qSort - but especially in the case where the input data is already sorted. in some stress tests which ran through the index with a lot of items, this commit provides huge speedup (684ms down to 10ms for painting 15001 empty items on the provided benchmark), for me.
