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. svn-id: r36177
