In a recent update, fetch()ing a .png file will now return a paletter-fitted u8 userdata, instead of the i32 we had before. Unless I've missed something, this means it's now no loner possible to get the actual colours in the image? Maybe an extra argument to fetch could resolve this, as we still have the ability to pass true to userdata :convert to get the palette alongside a u8.

Never mind, you can pass {argb = true} as a second arg to fetch().
