== Future: ==

Too difficult/complicated to implement:
 - reflowable text/combine lines/unwrapping
 - multi-thread

Not enough motivation/Lazy
 - commandline argument auto-completion
 - use absolute positioning for long whitespace
 - detect duplicate base fonts when embedding
 - disable selection if we know unicode is wrong
 - check if we can add information to the font, and let browsers show ligatures automatically
 - draw non-orthogonal lines with CSS
 - precise link destination: zoom
 - multiple charcode mapped to a same glyph
 - minimum line width of css drawing
 - separate classes for annotations (such that we don't have to hide all css drawings for printing)
 - Widget Annoataion
 - handle large negative letter space
 - optimization levels
