Hello, folks.  I've been playing around with LSC 3.01 (and enjoying it
greatly) and recently started messing with pixel patterns.  I haven't been
able to produce a pixel pattern that actually uses RGB colors.  What I've
done is createD a color window with NewCWindow, which works fine as far as
I can tell, and then attempt to fill a rect with my pixpat.  The pixpat
is created with MakeRGBPat; I've tried a variety of RGB colors as the
pattern specifier.  FillCRect, when given this pattern, fills my rect with
a pattern using only QuickDraw colors.  I've also tried using PmForeColor
with an index from 0 to 255 and painting an oval; this invariably gives
me black.

Soooo, do I somehow need to attach or specify a palette for use by my
CWindow?  Is there a good source for example Color QuickDraw code?  A 
fragment of my program:

    void doabout()
        {
        PixPatHandle  niftypattern;
        RGBColor      niftycolor;
        CWindowPtr    niftywindow;
        Rect          niftywinrect;

        /* set up rect "niftywinrect" here */
        /* build a sample RGB color in "niftycolor" here */
        
        niftypattern = NewPixPat();
        MakeRGBPat(niftypattern, &niftycolor);

        niftywindow = (CWindowPtr) NewCWindow(NULL, &niftywinrect, 
                      "\pNifty Window", TRUE, 4, (int *) -1, FALSE, 0);
        FillCRect(&niftywinrect, niftypattern);
        }

And another question... LSC didn't know about the CWindowPtr type, even
though I was including both Color.h and ColorToolbox.h.  I typedef'ed
CWindowPtr to be CGrafPtr.  Is this a problem?  Should I be including
something else (MacHeaders are enabled)?

Thanks for any help you can provide.
