My GSoC project spans into three PRs in three different projects of two separate organizations. The two organizations involved are Enigma-dev and Tiled. fundies and Josh are my mentors from Enigma-dev and bjorn is my mentor from Tiled.

• My first PR (this one which is main PR) #2302 goes in enigma-dev/enigma-dev repository
• Second PR #228 GSoC project: Tiled compatibility support RGM goes in enigma-dev/RadialGM repo
• Third PR #3435 GSoC project: Enigma importer plugin goes in mapeditor/tiled repo

Requirement: You have to use Arch linux OS specifically, as Enigma-dev's RadialGM only compiles in Arch linux at the time of writing these steps. Compiling RadialGM can be tough, so feel free to ping in enigma-dev discord server.

Steps to test the project:

1. Compile Enigma-dev's RadialGM project and Tiled projects. (Note that Enigma-dev's enigma-dev project is a submodule of RadialGM so it gets included with RadialGM)
2. Open terminal and change directory to RadialGM, checkout to PR #228
3. Change directory to RadialGM/Submodules/enigma-dev, checkout to PR #2302
4. Setup a system environment variable named ENIGMA_PATH and set its value to RadialGM/Submodules/enigma-dev. This path will be used by Tiled editor's "enigma" plugin.
5. Change directory to Tiled, checkout to PR #3435
6. Compile RadialGM and Tiled projects separately
7. Run RadialGM project to open RadialGM editor, test the TMX importer by importing some .tmx file
8. Run Tiled project to open Tiled editor, enable "enigma" plugin by checking it in Edit-Preferences-Plugins tab and finally test the EGM importer by importing some .egm file

• Add support to wangsets in TMX importer
• Add support to missing features of internal tileset in EGMRoom
• Add support to rest of missing TMX features in EGMRoom (needs updates in RadialGM renderer and enigma enigne)
• Fix Tiled ci which is breaking due to missing libEGM headers
