  I am trying to determine the most optimal parameters and image format 
  to XCreateImage that minimizes the work the server must do to display 
  an image via XPutImage.  I suspect creating the image data in the bit-order
  and byte-order of the server is most efficient, but I developed doubts when
  I looked at XImUtils.c and noticed the code normalizes all data to
  LSB byte-order and bit-order.  Is it more efficient to generate the image
  data in LSBFirst byte-order and bit-order?  Also are other parameters 
  crucial in minimizing server overhead.  For example, are 32 bit scanline 
  pads more efficient than 8 bit?

  This is the last issue I need to resolve before I make my image processing
  software available on expo.lcs.mit.edu in a few days.  A prompt reply
  will be appreciated.  Please Email your suggestions to cristy@dupont.com.
  Thanks in advance.
