I did not test adding the levels 19 and 21 yet.
Bad news: Adding just one level would blow up some limit. My largest tile .img is about 20 megabytes. Time to split my tiles again, I guess.
More bad news: After the additional splitting, my gmapsupp.img grew to 94 MB. Without the added levels and the splitting, it would be about 80 MB. The baseline (without the patch and splitting), it would be about 82 MB. I think that the growth is unacceptable.
My revised patch is attached, including the changes to the options, which I am reluctant to apply. If you have no objections, I would like to commit the changes to polygons and lines. Well then add a note to the options file, that while it is nicer and faster on the GPS to draw (if level 21 and 19 are included) - however it adds up 15% to filesize of gmapsupp.img (though I don't get how you get 15% when I get around 5% - well that's with exporting from Mapsource where the mdr file takes up quite a lot of space too). What is your commandline options?
Also I don't really sea why healthcare polygons should be visible already at resolution 22. I think 23 (so 24 for everyone who does not use 23) is enough. Essentially it's no more important than plain houses in my opinion. Besides - all my resolutions were the bare minimum change that I thought is needed (and that was before the drop small polygons patch got commited, which made a huge change too when used with default style-file). highway=service at 23 is another thing I'm not too happy. Often highway=service connect residential roads and tracks. That's why I put them to 22. Maybe a finer seperation would be needed using service=* tag.
