This fixes a bug that can reproduced with these steps:
* Start openttd in fullscreen mode
* Turn off fullscreen mode
* Try to resize the window. The window can't be resized.
This function requires libSDL 2.0.5 or higher. It looks like we don't
need to use it, and can just use the original SDL_CreateRGBSurface(),
with the masks set to 0, to trigger the default 8-bit format, which is
SDL_PIXELFORMAT_INDEX8.
Closes#7785
Note: this code path is activated by using an 8-bit blitter, like:
./bin/openttd -b 8bpp-simple
Many of these town names were using the 'a with ~ above it' character,
which should actually by 'a with u above it'. There were other missing
accents as well which I've added.
With language set to German, there was a problem in this dialog box due
to the long strings in this language. It looks like the call to
`GetStringHeight()` here is using `r.top` to help calculate the
max width, rather than `r.left`.
I've replaced some of the duplicate real town names with new real town
names in the French and Slovak sets.
Also, some Slovak town names were missing accents, so I've fixed those.
