 Summary of the bug:

 In the documentation for the "geq" filter all x and y must be replaced by
 capital letters X and Y, in the following lines. In the example section
 it's all written correct. It doesn't work with lower case.

 p(x, y)
     Return the value of the pixel at location (x,y) of the current plane.
 lum(x, y)
     Return the value of the pixel at location (x,y) of the luminance
 plane.
 cb(x, y)
     Return the value of the pixel at location (x,y) of the blue-difference
 chroma plane. Return 0 if there is no such plane.
 cr(x, y)
     Return the value of the pixel at location (x,y) of the red-difference
 chroma plane. Return 0 if there is no such plane.
 r(x, y)
 g(x, y)
 b(x, y)
     Return the value of the pixel at location (x,y) of the red/green/blue
 component. Return 0 if there is no such component.
 alpha(x, y)
     Return the value of the pixel at location (x,y) of the alpha plane.
 Return 0 if there is no such plane.

 For functions, if x and y are outside the area, the value will be
 automatically clipped to the closer edge.
