bug found in baidu(ubuntu...)

precise link dest

try harder finding glyph names (using fontforge) for CID Type 0

rename single-html -> embed-font/image/css ...

argument auto-completion
add fallback font for ' ', or create glyph for it

==Future==
use absolute positioning for long whitespace
color invert
detect duplicate base fonts when embedding
disable selection if we know unicode is wrong
combine lines (unwarp)
Printing
multiple charcode mapped to a same glyph
check if we can add information to the font, and let browsers show ligatures automatically
native support for image
native support for draw
