if you can use opengl, then it's easy (and super fast. filled triangles
are the most basic shape in opengl).
It you want to stick to the SDL renderer API, one possibility is the
following:
* draw a rotated filled rectangle on a TARGET texture
* clip two corners by blitting a suitably rotated texture with 0 color
