This commit expands tabs to spaces (ts=4) in all the files under src/
and test/.
Until now we had two wildly different code styles with C using tabs and
new C++ using spaces. It is painful to maintain as none of the commonly
used tools support this kind of setup and in reality is needless, as we
can simply convert all the sources to spaces and have opened PRs do the
same, where needed.
Additionally, trailing whitespace has been removed.
Create a dummy UI context and use that if headless is enabled. Some extra guards added to deal with the return values from the dummy class. It may be temporary until the window and input code is moved to openrct2ui.
Both horizontal and vertical scrollbars had a malfunctioning widget: both the
right and bottom widgets weren't fired properly.
The bug was less noticeable for vertical scrollbars, as clicking the widget would
be treated as clicking empty space, which did not happen for the horizontal
scrollbar.
This patch fixes the underlying inconsistencies, making sure the widgets for
both types of scrollbars work -- when using either scrollbar, or when combined.
