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 and performance 
considerations?  I'm pretty new to the GUI classes, so I may need some in-depth 
guidance on this.

Thanks...
