Better Texture Atlas [1.2.0]

Full Changelog: 1.1.0...1.2.0

We are releasing this update because BTA has been under heavy development since the start of 2025, but those new features and fixes haven't received consistent releases. After this release, BTA development may remain silent for a while, except for the occasional bug fix. We believe the code for this plugin is very outdated, and we could do much better with a rewrite.
