Well -- it's not about the selection per se here, right?. It's about computing 
with alpha, so wouldn't something like

inverseAverageAlpha(Q_UINT8 * pixel, Q_UINT8 * alph2)
averageAlpha(Q_UINT8 * pixel, Q_UINT8 * alph2) 

be better?

Or maybe:

mask (Q_UINT8 * pixels, Q_UINT8 * mask, Q_UINT32 nPixels)
inverseMask (Q_UINT8 * pixels, Q_UINT8 * mask, Q_UINT32 nPixels)

?

Give me some time to complete the !@#$% renaming...
