In the spirit of programming tutorials, we’ll start by creating a very basic “hello, world” texture that can then be loaded with SDL. Here, we will use the free tool Grafx2 on Windows, but any and all graphic tools that can save BMP format will do.
In this tutorial I’ll use the Terminus font with the gq2 and td1 variants. For Windows it comes with a neat installer that allows you to choose the patches easily.
