This is intended for the built-in 8x8 bitmap characters and quake's "conchars", but could potentially be used for any simple (non-composed characters) mono-spaced font. Currently, the buffers can be created, destroyed, cleared, scrolled vertically in either direction, and rendered to the screen in a single blast. One of the reasons for creating the buffer is to make it so scaling can be supported in the sw renderer.
