On a mailing list, someone pointed out a Windows lcd test program that was useful for adjusting the pixel clock frequency and phase of LCD monitors with analog VGA inputs (vs. DVI). It puts up alternating white and black vertical lines one pixel wide. This is useful either for auto-setup or for fine tuning.
lcdtest was able to do that, but you had to type the five key sequence ``wv0-'' to get it. So I've added the command ``a'' to do it with a single key.
I also added command line options to list the available video resolutions, select a resolution, and get help. There's a new option to display in a window, intended for debugging and example screenshots.
I now consider the program to be feature complete, so the new release is version 1.00.
