TUI font rendering is _very_ slow

[d3zd3z]

The text is rendered a pixel at a time, which will be thousands to millions of times slower than more specialized code. If we're going to stick with bitmap fonts, there are some good examples of the kind of bitblt we need in the X11 code (is this license compatible).

The current code is certainly functional, but coming up with better text rending will likely be important to make the UI usable.

TUI stuff was removed in #1844.
