The pango backend now correctly draws colored or uncolored backgrounds.
This is needed to support drawing cursors.
We currently do not optimize this for performance. In fact, this reduces
performance a lot and we could avoid drawing backgrounds if we cleared the
background to the same color before. However, this also means we currently
could move drawing the background into the console backend again. The
transparency feature is awful, anyway and I don't see any reason
supporting it.

This adds support for colored and bold characters. This also adds the
infrastrucure for background colors and underlined characters, however,
these are not properly implemented, yet.
The color codes are similar to xterm and optimized on black backgrounds.
So they are not too bright or shiny.

We now assume a screen of -1,-1 to 1,1 instead of 0,0 to 1,1 to avoid
matrix transformations.

The old font-renderer was horribly slow. There were several ideas to
speed it up but I decided to add the pango backend again. Pango allows us
to draw combined-characters and all other kinds of special characters. We
would have to rewrite pango if we wouldn't want this dependency so I
currently have no idea why we should make it optional.
However, some people might not care whether they can correctly display all
kind of Unicode text but instead want some shiny kmscon without any
dependencies. Therefore, I will keep the old freetype font-renderer even
though it is not used yet. However, we can convert it at any time.
The new font-renderer is not used yet. We need to cleanup the console
layer first before it can be hooked into the terminal.

We now properly draw fonts with OpenGL. We now use FreeType2 instead of
pango to avoid big dependencies.
We also add a DejaVu font so we currently don't have to deal with font
selection.

To avoid cairo dependencies we now take a compositor reference in the
font backend so fonts can be drawn with GL textures instead of cairo.

We use a new font factory which is used to create a new font. It will later also
be used to cache fonts and select proper system fonts.
