Clang-format sees the text behind `#pragma region` as code and formats it. Instead of stating the copyright and date there, it's now in the comment block right below it. The text "Copyright" is left in the `#pragma region` line, as clang-format sees it as a single identifier.
I took the opportunity to normalize the dates, and add the copyright notice to the source files where it was missing them (except for third-party and the generated resources.h file).
This adds a warning to track preview window explaining it's not
supported with OpenGL renderer. Also fixes the issue whereby no stats
were printed because of early exit.
This removes most usages of the separate flag, instead relying on ride groups to do its job.
Research is more complicated and will follow in another commit.
This adds a vector of indices used for the track designs array, which is
used instead of the window list index.
Some other things I've edited that are not directly related to this
commit:
- Orders widgets in logical order like how they appear on screen
- Adds some comments to existing code
Regression from #6574. Restoring the backup of SPR_TEMP was removed which was necessary as it is the sprite for grass tile zoomed out. Instead make SPR_TEMP a special sprite ID which is not used for anything else apart from temporary sprite drawing.
