draw_background_tiled_partial_ext

Expand/*
**  Usage:
**      draw_background_tiled_partial_ext(background,x,y,xscale,yscale,rot,color,alpha,index)
**
**  Arguments:
**      back    the background to be drawn.
**      x       the x position of the background.
**      y       the y position of the background.
**      xscale  the hor. scale of the background.
**      yscale  the ver. scale of the background.
**      rot     the angle of the background.
**      color   the color of the background.
**      alpha   the alpha transparency of the background.
**      index   to check if the background is tiled vertically.
**
**  Notes:
**      Don't change the value of the 'top' variable. That will make the background get drawn as many pixels the background has below the top background.
**
**  Returns:
**      Returns a drawn background depending if it's tiled horizontally i/o vertically.
**
**  Example:
**      draw_background_tiled_partial_ext(background_index[0],view_xview[0]/2,0,1,1,0,background_blend[0],background_alpha[0]);

Re: draw_background_tiled_partial_ext

Can you provide a description of what this does and perhaps an example how one would use it?
