We now generate GIF images for visualizations and add inline
references to them in the HTML output.
Images are scaled using the HTML img properties. This works well
on some browsers, but others insist on "smooth" scaling that blurs
out the pixels. This may require a workaround.
An extra blank line is now added above visualizations. This helps
keep the image and data visually grouped.
The Apple II bitmap test project was updated to have a visualization
set with multiple images at the top of the file.
Having underlined blue text everywhere was too noisy. This changes
the CSS style for internal links to be plain black text that gets
blue and underliney when you hover the mouse over it.
Also, added the current date and time to the set of template
substitutions.
