QVector copying data with remove()

[Momergil]

Unless QVector is forced upon you by some interface

Yep! I'm using Qwt which uses a QVector<QPointF> internally to storage the plotting data :T So I can't avoid using QVector for the plotting, although it maybe faster to copy a entire new data to a QVector instead of using append + remove(0,1); but I wouldn't know that.
