Run Adobe Photoshop CS.
Open an image.  Go to Filter / Filter Gallery.
Open up each of the filter groups in turn.
The gallery is supposed to show a sample
of each filter applied to a sample image,
but the filtered sample images are really
hard to make out, they don't seem to be displayed
properly.

Created an attachment (id=7844)
 --> (http://bugs.winehq.org/attachment.cgi?id=7844)
patches

This bug is caused by AlphaBlend ignoring the blendFunction.AlphaFormat field.
Currently we assume it's value is AC_SRC_ALPHA - the alpha data is available
for each pixel as an alpha channel in the DIB. However if this field is 0 we
should assume that each pixel have a constant alpha (it's written in a very
unclear way in the MSDN that this value is valid). With this patch the filter
gallery seems to be drawn correctly.

I don't know if this way of solving it is the best or there is a way to ask
XRender to do it for us. I will try to find some documentation of it. Also even
with this patch we ignore SourceConstantAlpha (Photoshop filter gallery doesn't
use it) - a factor by which we rescale the alpha values. It's probably rarely
used if there is an alpha channel but it's the way to manipulate transparency
without an alpha channel. Adding it only for the later case is trivial but I
will search if there is a way that would work for both 0 and AC_SRC_ALPHA.

The patch http://www.winehq.org/pipermail/wine-cvs/2007-August/035803.html went
into Git and will be in Wine releases starting from Wine 0.9.45.
