makebevel - turns an input GIF or RGB file into a button by making its edges beveled.
usage: makebevel inimage outimage [width] [-sgi]
makebevel can read gif and rgb formats and output both as well. The correct file format of the input image file is determined by the file extension so this must be correct. For GIF-format, use either .gif or .GIF. For SGI's RGB-format, use .rgb or .RGB.
makebevel saves to GIF-format as a default but can save to RGB if the -sgi option is given at the end of the command line. (see usage) If no width is given, it defaults to a width of 5 pixels.
