I think all of those examples are simply conversions to other formats,
they don't change the contents of the files. This could be added to the
'Definitions' section of the license.

From the zlib license:
1. The origin of this software must not be misrepresented; you must not
claim that you wrote the original software. If you use this software
in a product, an acknowledgment in the product documentation would be
appreciated but is not required.
We could change the last sentence from "not required" to "required"
and add the part about having a link to www.ldraw.org.
Actually the zlib license is very simple, it only has 2 more
paragraphs:
2. Altered source versions must be plainly marked as such, and must
not be
misrepresented as being the original software.
3. This notice may not be removed or altered from any source
distribution.

Maybe requiring a 'changelog' to be included would be better ?

How about: "Any parts that have their contents changed must have the
line "Original/Official ..." removed" ?

Sounds reasonable. All we need to do is change "New files added to the
library can have any license." to "New parts can only be distributed
with the library if they are published under this license, otherwise
they must be distributed separately.". Now we'll need to define
'separately' :)

I think only in a few cases it does: A float is 4 bytes, so if you
have 3 ASCII digits plus a space then both formats have the same size
but if you get a number with decimal places then the binary format will
usually be smaller.
