Dear Chee,

  Sorry I am not able to finish to "worm" part before I leave.
I will continue after I get back.

  Right now, the clean version is at 

/home/visual/usr/yentj/yap/new

  The list of keyboard commands is in the README file.

  Also, I fix the "g" command which will get a 200x200 area.
It was not working in the old version.

Dear Chee,

  I have made some changes in opengl panning program.

  First, the zooming is working as you said.  The commands are
"i" and "o" for zoom in/out.  The key "o" was used for reading
the saved file.  I changed it into "R".

  Two other keys are "0" and "1".  "0" is for debugging information
about the numbers of bits for RGB colors.  It will be printed
to standard output.  "1" is to toggle the on-screen scale/pan information.

  I also enable the arrow keys for panning.  It is in the function
mySpclKeys().

  I split the app3.cc into three parts.  The first part is
RGBpixmap.h/cc.  It contains the classes mRGB and RGBpixmap.

The second part is points.h/cc.  It contains other classes
by the RGBpixmap.cc.  (It is not very correct.  Some classes
in this file is not used.)

The third part is aux.h/cc.  It contains some auxiliary classes
which are not used for panning.

  You can get the files from

/home/visual/usr/yentj/yap/new/
