title: image background - how to repeat image as background rather than stretch it
body: <p>I have an image I want to use as a background to some layout.
  the problem is the image contains a texture of slant lines, so if i use a 1 pixel width image or a 9 patch the image is stretched and the texture is Twitching, so i can see the slant lines as latitude lines.
  I saw that he android emulator uses a similar texture in the progress bar indeterminate animation, is there a special/simple definition to order the background image to repeat itself rather than stretch? is there a way to do it with 9 patch, cause eventualy i also need the corners to be round.
  thanks for the help.</p>
