If we're improving the plotters, can we get this fixed at the same
time? Colours should be in 0xRRGGBBAA on big-endian platforms, same
as the bitmaps.

Opening and closing fonts here is relatively slow, so I'd like to keep
it to a minimum. Can we assume that find_font should also open the
font in question? How do we find out when NetSurf has finished with
it (for the page)? Some way of keeping track of usage in the platform
code and being able to flush any that have not been used for a while
would be useful here I think.
Regarding generic families, the easiest thing would be for NetSurf to
send the user's selected font for the desired family (from
option_font_sans etc) in the font_names array.
