That's it. All textures are mip-mapped the first time they are displayed.
So, one must display all textures when (or just after) the DB is loaded.
That's why perfly shows all textures before entering in the 'drive' mode.

It's not mandatory to display the texture, one can use the back-buffer to draw
a polygon per texture when displaying something else on the front-buffer.

In libpfutil, a smart function called pfuMakeTexList() construct a list of
textures by traversing the scene graph, pfuDownloadTexList() will do the
downloading job. Look at the man pages for more informations.
