[Feature Request] Stroke width/outline for text in bitmap backend #615

What is the feature ?

It would be useful if we could draw text with a colored outline. This is useful when wanting to label parts of an image.

(Optional) Additional Information

I have tried drawing the text in black four times (transalted by 1px in the four directions) behind the main text, but the results look ugly for some reason.
