Ok, before I go and start hacking out my own solution, I would
like some feedback.  What I want to do is quite simple.  I want
to draw a line in a window, 5 pixels wide (ie - by calling
GpiLine).  
First, I took the obvious (or at least it seemed obvious approach): 
I tried setting the cosmetic width with GpiSetLineWidth.  The function
returned and 'ok' but no go, the line came out thin.  So after doing
some reading, I figured I should check the device capabilities for
CAPS_COSMETIC_WIDELINE_SUPPORT with a call to DevQueryCaps (under
CAPS_ADDITIONAL_GRAPHICS).  
Well, the results say it isn't supported.  Why not?  Will the 32bit
GRE 'fix' this? 
What devices do support cosmetic wide lines? (I would guess at least
postcript)
Am I missing something really obvious (that would keep me from drawing
multiple 'thin' lines to make one fatso)?  

Thanks..
