[Dillo-dev] long lines and slowness (common when viewing style sheets)

Now that everyone likes to send their style sheets as one big long line, like 250k long, viewing them in dillo is slow. gprof says % cumulative self self total time seconds seconds calls s/call s/call name 32.47 1.88 1.88 189407242 0.00 0.00 lout::misc::NotSoSimpleVector<dw::Textblock::Word>::getRef(int) const 29.36 3.58 1.70 187437456 0.00 0.00 dw::Textblock::BadnessAndPenalty::lineCanBeBroken(int) 28.15 5.21 1.63 29345 0.00 0.00 dw::Textblock::wrapWordInFlow(int, bool) and I wonder whether any optimizations are possible.
