Tux Paint 0.9.28

What's new in this version:

Fixed:
- Fixed abnormal exit of threaded font scan which prevented enablingtext/label tools on some environment such as Rocky Linux 8.
- Pass the full path of locale directory to bindtextdomain().Workaround to the issue that gettext() can not find translation
files after the update of MinGW/MSYS2 in January 2022.
- Initializing layout of onscreen keyboard (osk) to avoid undefinedbehavior when changing keyboards.
- Address issue with uppercase-only mode in Turkish locale.
- Fixed a bug that can randomly crash Tux Paint when started in a languagewith a input method map (*.im)
- Avoid leaking memory when loading Label text strings from asaved drawing. (Affected Windows only.)
- Avoid crashes when coming across unexpected Label data stored within a saved PNG image.

- Adjust where libpaper gets init'd.

Ports & Building:
- Release builds tarballs that denote SDL1.2 vs SDL2.0 branch

- On macOS, use the CMD key wherever CTRL is used on other OSes

- Use character class in macOS build script (It appears t is not compatible with certain versions of grep.)

- Remove install stages not needed on macOS

- When looking up paths of fonts, preferences, etc., macOS searches two places, the system paths and the user paths under $HOME.
Now handling rare scenario where HOME is not set; if so, now just searching the system path twice instead of searching the
system path followed by going into an undefined behavior (possibly segfault crash).

- Fonts are now also looked for in the system preferences path, /Library/Application Support/TuxPaint/fonts

- Fixed the issue with the backspace not working in text and label tools when in certain language modes in macOS.  Mac keyboards have the DELETE key where PC keyboards have the BACKSPACE key, and the two keys have different keycodes, so the backspace requires special handling on the macOS in programs writtens for the PC.
