Navit patch for faster map dragging

[Lothar Behrens]

Hi,

I have another idea that propably improves the 'speed'.

Why not prerender the other 8 rectangles of the screen that would then
have an effect to scroll in faster when the map is dragged in any
direction ?

In normal circumstances the user has to do with reading the map, thus
the CPU has time to do such prerendering.

There would also no more than the 9th of the screen prerendered, because
you can not scroll more.

If the user drags repeadedly in one direction, only the relevant new
areas need to be prerendered.

Is this possible or realistic ?
