Feature request: Draw text without affecting background color

[flautines]

I wanted to add some shadow/3d effects to the texts I draw. A very common trick to do that is to draw the same text slightly off by several pixels with a darker color and then draw the same text over with a lighter color.

But to do that the background color must not be changed on successive calls to draw text, or the effect is completely ruined.

Would it be possible to add an option not to draw any background color when drawing text (perhaps by adding a special numeric value to setBackgroundcolor())?
