Background of transparent png always black when exporting

[fabb]

When loading a png file with transparency and exporting it as jpg, the transparent areas turn black. It would be nice if the color could be selected (for my use case I would need white).

See #485 (comment) for a workaround.

Hm, couldn‘t that be a problem when i don‘t know if i load a jpg or a png?

I would suggest to add an option to color the canvas area before loading the image into the canvas.

Maybe you can put it behind a if(image.alpha) ?

This is not an easy option to add, because we don't create the array that holds the data. It comes directly from the decoder libraries.
