ColorLayer position is wrong (with fix) #106

On the on_enter method of the color layer, the vertex buffer is created relative to the it's position:

x, y = self.width, self.height ox, oy = self.position

    self._vertex_list = self._batch.add(4, pyglet.gl.GL_QUADS, None,
        ('v2i', ( ox, oy,
                  ox, oy + y,
                  ox+x, oy+y, 
                  ox+x, oy)),
        'c4B')

BUT, on the draw method the transform is applied by an opengl matrix causing the vertex list to be drawn with twice the offset given by position

Changing

ox, oy = self.position

to

ox, oy = (0, 0)

fixes the problem :)
