mdomlop/retrosmart-x11-cursors ? reverse-engineered prompt

Build me a retro X11 cursor theme called Retrosmart that feels like old Windows 3.x and classic Mac cursors, with that old school desktop look. I want it to come in a white version and a black version, and each one should also work with and without alpha shading.

Please make it so someone can build it with a simple make command, install it system wide, and uninstall it cleanly too. If it makes sense, add a way to generate the final cursor files from the source artwork and include a simple preview page or test page so I can see the cursors before installing them.

Use whatever workflow is best for turning the source artwork into X11 cursors, and look up current docs online if you need to. Keep it practical, easy to build, and ready to package for Linux users.
