The more stuff I add to minifb the more I actually want to use it in some other projects (like ProDBG) as I'm almost doing double work/cut'n'pasta now. So I have considered extending minifb somewhat that might break the current API.
Window::new(title, width, heigh...) <- this is all good but i'm thinking off perhaps adding something like
Window::new(title, width, height, Option<Scale>, Option<WindowStyle>) (style is for resize and such)
window::update_with_buffer(&buffer) <- rename of the current update function.
Sounds good then! Being able to use a separate OpenGL context will be definitely beneficial for some users.
