KNOWN BUGS
----------
On macOS 10.13 High Sierra:
- The mouse cursor appears with an invert-transparent background due to an
issue with SDL1 on macOS 10.13. A patch to SDL has been issued on May 16,
2018 to fix this issue. Until this patch is officially relased and becomes a
part of the MacPorts package, SDL will need to be built from the source code
that includes the patch to display the mouse cursor correctly under macOS 10.13.
Here are more details:

- It is no longer possible to build Tux Paint that is backward compatible with
older versions of macOS than the one on which it is built using the procedure
described in the below section, "BACKWARD COMPATIBILITY". This limitation
appears to stem from some libraries required by Tux Paint now being built
using Rust that is unable to produce libraries that are backward compatible
with older versions of macOS. The steps of the procedure are left intact
below anyway in case the situation changes in the near future, with the
exception that what once-referenced 10.7 now reference 10.8, believed to be
the oldest version of macOS that Tux Paint could be backward compatible with*
once the Rust issue has been addressed.
BACKWARD COMPATIBILITY
----------------------
Broadly speaking, a Mac binary built on macOS 10.12 Sierra (for example) runs
only on macOS 10.12 and later. To compile a binary that can also execute on an
earlier version of macOS (say, 10.7 Lion and later), one of the following must
be done:

(A) Pass the flag -mmacosx-version-min=10.8 to the compiler.

To build the Tux Paint package that can run on earlier versions of macOS, the
MacPorts libraries also need to be built with either #1 or #2. This is done by
configuring MacPorts to install all packages from their sources and build them
to run on macOS 10.7 and later:
to run on macOS 10.8 and later:
1. Install the MacPorts base normally.

Even when Tux Paint and MacPorts are built to run on a specific version of
