Vertex Colours: Sample True Local Colour

Sampling (with "s" hotkey) in Vertex Paint Mode samples the screen colours, not the true vertex colour of the object.

This is not the expected behavior. If I'm sampling in Vertex Paint Mode, I want to sample the exact vertex colour to be able to re-use it or save as a swatch, not an approximate version of it that's affected by the lighting.

If sampling from screen-colours is actually useful (I'm not aware of any case that it would be), by all means let me know why it should take priority. Otherwise I propose it is relegated to an optional setting in the toolbar, and the default behavior samples the true "flat" vertex colour instead.
