Subject: Merged r36175 from branch-0-13-0:

Fixed alpha blending in the UI dialogs by adding alpha
computation to the blendPixelPtr() function.  To minimize
impact, pre-multiplied alpha is assumed, meaning that the
blending of the R, G and B components is the same both
with and without hardware alpha.
