Downloads latest debian GTK3 source, patches to fix annoyances, and compiles.

#! /bin/bash

# for this to work correctly, make an empty directory and put this shellscript inside it, along with the patch  'gtk3_make_filechooser_not_suck.patch'.

# Running this in a directory with a previous gtk source tree or any other files or directories may make this script behave unexpectedly!

# the patch file is found at:
# https://gist.github.com/wyatt8740/ae82550264564e2bba49b58d3e07f0f5.
# raw patch file (direct link):

# This script does not perform installation as that requires root privileges. A 'make install' should suffice.
# The configure flags are, as far as I can tell, the ones used by Debian for official builds. I initially had built it without broadway or wayland and started getting
# segfaults with some debian-packaged programs, so they are important to leave intact.
