Code

The union of the color and the node_number in the struct screen_char.

Browse Source 
The long term goal is good looking of the Python docs in ELinks, especially
background colors. Every start tag and every text node would have associated
a natural number. Those numbers would be "drawn" in the document instead
of colors. Finally, the screen driver would change numbers into colors.

This will be done in small steps. The next step is to implement this change
in the screen driver.
