example:
-m '32-255' select gylphs from encoding 32 to 255
-m '32-255,~64' select gylphs from encoding 32 to 255, exclude '@'
-m '32,48-57' select space, '1', '2', ... '9'
build modes:
-b 0: Most compact, glyph bitmap is minimal
-b 1: Like -b 0, but glyph bitmap is extended to the height of the largest glyph within the selected glyph list.
Also the width of the gylphs is extended to cover the delta x advance.
-b 2: Like -b 1, but glyph width is set to the width of the largest glyph within the selected gylph list.
-b 3: Like -b 2, but width and height are forced to be a multiple of 8.
