lcdtest is more popular than expected

Judging by the Freshmeat stats, lcdtest is way more popular than I ever would have guessed. There must have been some unsatisfied demand for a test pattern generator. Perhaps I’ll build Windows and MacOS X binaries for it as well. There already are some similar programs for those platforms, but perhaps there’s some utility in having a common cross-platform program, and anyhow, since I used SDL it should be easy.
