Re: [2/3] gdiplus: Round up when converting from 32-bit ARGB to PARGB.

[Vincent Povirk]

Are you sure about this?

Other tests have suggested that native is not this exact when dealing
with color values, and different OS versions have produced slightly
different results.

Is there an application that relies on this, or is there a reason this
is generally more correct behavior when premultiplying alpha?
