Best way to draw image in menu title?

[Jason Clouse]

I'm plinking around with a theme bundle to match my WindowMaker theme.  I'm 
trying to draw an image into the menu titlebar (NSMenuWindowTitleView, drawRect 
method).  What's currently there is this:

  [[NSColor windowFrameColor] set];
  NSRectFill(workRect);

There is an NSDrawBitmap() function, but the Apple docs say it might be more 
useful to employ the NSBitmapImageRep class; though there are plenty of other 
bitmap and image classes too.  The question: which class do you guys think 
would be best for this task, both for functionality (scaling AND tiling, as 
well as shading the borders of the image) and performance considerations?  I'm 
pretty new to the GUI classes, so I may need some in-depth guidance on this.

Thanks...
