There are (at least) three things that still need to get fixed for the flat 
projection:

- In Topographic mode at low zoom Marble paints parts of asia white sometimes
- The GPS layer doesn't get painted in flat projection using the correct 
projection (it still paints spherical. I guess you need to "port" the method 
that returns back the position in AbstractLayer.
- The number of cities painted is much lower than for the spherical 
projection. There is a variable in Marble which holds the maximum number of 
cities displayed. I guess there is something calculated wrongly with regard 
to that in the flat projection.

And it would be nice if you could analyze why the flat projection is so much 
slower than the spherical projection. right now. 
There is a "workaround" to speed this up a lot, but I guess there is also a 
bug that might cause the current slow painting.

Torsten
