Windows using the full height of a building part are not rendered

[HikeAndMap]

Hi there Tordanik, thank you again for the great work! Just recently found out we can add windows too .

I have an issue with it, not sure if it's a bug, probably not, but should be communicated with the community I think on the proposal wiki for windows.

if a window is between concrete beams and covers 100% of the area between 2 beams the only way for me to add windows is define a wall there and then say the window must be rendered in/on that wall.

So if a lower beam has min_height=4.60 and height=5.00
and the upper beam has min_height=7.60 and height=8.00
the space between is then 7.60-5.00 = 2.60 so the mapper would add a wall between with min_height=5.00 and height=7.60

Now since the mapper would want the windows to go all the way from the bottom to the top he'd map
window:breast=0 and window:height=2.60

And now the windows won't be rendered. The mapper is wondering:"huh, what's wrong?" it's simply not visible.

Took me also a while to figure it out.
But the trick here is to set window:height=2.59 now it's being rendered.

So the window really has to be INSIDE the wall - even if the wall is fictive just to be able to add the window rendering node to that wall - the windows can not span 100% of the area but always -0.01 to make sure it's being rendered.

So maybe not a bug - although I do think the windows should be rendered between the 2 beams, but the -0.01 is a neat trick to get it done anyway.
But then one might consider to update the wiki on windows for your proposal to inform mappers:"the window:height+window:breast must be smaller than the height of the wall they're embedded into. If they're equal - they won't be rendered.

Again, I do think it should be possible that a window is rendered to equal height, but if not possible programmatically then consider adding this little piece of information to the wiki on windows to always keep the window:beast+window:height < height(of the wall)

This is what I'm working on now , the building on the right side on the screen where you can see I'm adding now windows too to the building..

I'll make sure the whole Motorpool Compound of our city Engineers will be 3D on OpenStreetMap hopefully as an example to others how to do 3D mapping of buildings

And yes that out of proportion building looking like some "way too big" horse stables compared to the big office building in the lower right is correctly mapped. Actually it is that big because it's being used as storage for sand, gravel, and other materials for the city engineers.

It looks really wrong, but it's actually correct.. it's simply put oversized to cover the "mountains" of sand and gravel from rain
