If we want to skip transparency and just allow changing the background
to any other solid color, it looks like it's pretty easy for a
bare-bones fix: just add this as line 736 (in r59357) of texutil.ml:
| "\\pagecolor" -> (tex_use_color (); LITERAL (TEX_ONLY
"\\pagecolor"))
Then people can use the "\pagecolor{...}" command to change the
background just as they can use "\color{...}" now to change the
foreground color (see [[m:Help:Math#Color]]).
