[wxMSW 2.8] alpha+antialiasing support

[Chad Wagner]

I hope these aren't stupid questions, I'm usually on a Mac platform,  
and I've searched for answers without any luck.  Answers in the form  
of "duh, look here" are happily accepted ;-p

My gui uses all custom controls, consisting of various bitmaps (png  
with alpha), lines, splines, text, etc. all of which at some point  
utilize the alpha channel.  On Mac, I can draw a semi-transparent  
line by setting the pen with a color using alpha e.g. dc.SetPen(wxPen 
(wxColor(255,255,255,127))); dc.DrawLine(x1,y1,x2,y2);  The line is  
anti-aliased so it appears smooth, and the alpha value of the color  
is used appropriately.

porting to wxMSW, this is not the case.  the line is jagged and the  
alpha is disregarded.  is there a way to do this, is there a  
different module or feature I need to enable, an entirely different  
method I haven't thought of to circumvent the issue, or how is this  
usually handled?  is there something completely basic that I'm just  
overlooking? (I'm also quite sleep-deprived!)  It looks so terrible  
I'm sure there has to be a way...

any advice is greatly appreciated.

thanks,
chad
