Costom resolution support

[CodeExplorer123]

Hello, I'm a new user working on an e-paper display project and loving your program! However, I'm stuck with a display that operates at 250x122 pixels, which isn't currently supported. Adding this resolution option would be a huge help, however maybe it's possible to implement an option for custom resolutions?

Thanks!

Will think about custom size. I like this idea
