How to draw background?

[Mattias Gaertner <nc-gaertnma netcologne de>]

Hi all,

I want to draw a rectangular area in the theme button background.
For example: If the current theme defines a gradient from white to gray for button background, then I want to draw this gradient from white to gray. If it has a tiled picture as background, I want this.
How can this be achieved?
