Time to heat things up!
The new patch replaces almost the complete character rendering, and
draws directly to the osd display buffers. Render time is now down to
0.172s, giving a speed boost of 4.3x. :)

On a side note - Displaying the current page again only needs 0.08s, I
guess this is due to reading from same disk buffers again.
