css: tweaks when printing

[superzazu]

Hello!

A recent comment in SDL issue 9440 made me think that the wiki's CSS could use some tweaks when "printing" a page — whether we're printing to paper or just output to PDF (which is more likely, I suppose?).

Here are the changes (only when printing):

• font-size is set to 12px (instead of 16px)
• visited links are not in a different colour
• header + footer (+ ".anchorText") are hidden

I did not hide the [ edit | delete | history | feedback | raw ] line because I could not select it easily. Putting this line in a span or div with a custom class (eg "editButtons") for example would make this easier to do.

"SDL_CreateWindow" page printed as PDF using Safari: SDL3:SDL_CreateWindow - SDL Wiki.pdf

On another note, I'm wondering if outputting the contents of all wiki pages to a single HTML file and trying to output it as PDF from a browser would be a good idea. This would need some changes (such as rewriting links as anchors instead of URL to be able to navigate inside the PDF) but I guess that would fix some problems you had, like code blocks that run off the end of the paper. I'm trying to tweak the wikiheaders.pl file, but I don't know perl so this takes time.

Have a good day
