I've just added this to git. Not sure at what point it disappeared,
perhaps it was never there...

That font texture png came from an ogre project iirc, which used to have
a tool that rendered a ttf into a texture map, but this seems to have
been removed (according to a casual google search, perhaps it's still
out there somewhere).

Of course, these days it would be possible to render a font map texture
from a ttf with fluxus using the type primitive.

text-params was something I added during at the last minute on a TGV
train before the first performance of scheme bricks in an attempt to
make the build-text font it uses more readable by exposing all the
texture mapping parameters for tweaking. 

Done properly this stuff would be metadata added to the texture - which
would also allow things like proportional characters.

So to recap - build-text is very old code, but can still be useful for
debugging and general hacky, or small text, build-type does things
properly but is a bit slower and results in real geometry.
