I tend to agree more with Paul Heckbert.  The difference is that you
are describing an expression like 'bitmapped image' , while Paul means the
replacement of the word 'image' by the word 'bitmap' as in 
'I have a color bitmap of the mandrill' meaning of course, 'a color digitized
picture of the mandrill', or something resonably close.

A more appropriate expression could've been a 'bytemap' (Geesh!) for an
8 bpp image.

I also think that it's not clear if the 'new' meaning of bitmap means just
image or digitized image.  It's a bit awkward to hear things like
'your ray-tracer produces wonderful bitmaps'  (???)
