[Tilesathome] improvements for lines2curves.pl (BezierCurves)

[Martin Ždila]

Hello

We are using slightly modified tiles at home project to render map of Slovakia
at http://www.freemap.sk/. To make the map nicer, we are using
lines2curves.pl.

I found 2 problems there:

1. The script doesn't handle inner ways of multipolygons. Please check my
patch that fixes this issue: http://pastebin.com/G92Khdda

2. last line segment of the polygon is not curved. Currently I can easily
fix this problem because it is "slightly" more complicated than previous
one.
Small improvement is gained if
    while (@$points_ref >= 3) {
is replaced by
    while (@$points_ref >= 2) {

This way only last node is left sharp, but the previous one is "weirdly"
curved.

Could this be fixed? I can attach a very small example (osm and svg file),
but I am not sure if this mailing list supports attachments.

Thanks in advance
Best regards
