Sorry for not having a .tar extension on the prescaled icons file, that is now corrected.
Trac 288 changes the tool that navit_svg2png uses for prescaling icons. Rsvg-convert is a smaller footprint to install on Ubuntu and inside Scratchbox than the ksvg2png tool originally used. Now in SVN 200x.
#285: Fix some svg format icons files fixes a bunch of .svg files so that rsvg-convert can act on them. This also fixes the messed up gui_quit icon. Now in SVN 200x
#284: Improve menu performance on N8×0 This forces gui/internal to look for prescaled icons first, instead of trying to get libosso to scale them. The default sizes are 8, 16, 32, 48. Now in SVN 200x.
#283: gtk_drawing does not exit properly This fixes gtk_drawing so that the Close icon (X in top RH corner) calls an orderly close function. This patch is not needed if you are using gui/gtk. Now in SVN200x
#282: Screen unblank support for Nokia N8×0 This keeps the N8×0 screen unblanked if you are in Fullscreen (by default). The Navit team is working to implement this in general way for other platforms as well, my way is very Osso specific. In the end Navit will need to call Osso on the N8×0 but there will be hooks for other platforms to do it their way.
I updated the navit wiki with more details on compiling Navit for the N8×0.
