Also fixes an issue where program exits when terminal resized but
only after all the wipes have finished. You can now resize the
terminal, before, during and after the wipes have completed and
the windows are now all correctly updated and sized.
Updated version to 0.28-pre-release
Removed unnecessary zero of gui thread pointer.
Created six new functions in gui.c in order to fix the above problem
and reduce existing duplicated code.
Since these modules are considered third-party (at
least for now) and we also don't want to apply
formatting to them.
Also removed the `AUTOMAKE_OPTIONS` from `Makefile.am` since
it would appear the `AM_INIT_AUTOMAKE` is actually defining
the automake options.
This fixes the following AC warning:
```
configure.ac:6: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see:
configure.ac:6: https://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
```
As per the deprecation notice, using `AM_INIT_AUTOMAKE` for setting the
version is mostly obsolete because the package and version can be obtained
from Autoconf’s `AC_INIT` macro.
When there's no pkg-config file for the panel library, the build breaks
if the header is not in /usr/include.
At least in openSUSE, we have /usr/include/ncurses.h and
/usr/include/ncurses/panel.h.
