    Fixed some issues with B-spline curve rendering: · 5ab286a5

    - Texture allocation in constructor didn't initialize data so caused glitches as soon as the picktoolbar appeared.
    -> Textures are now created AND initialized on demand (at first selection update).
    
    - The texture for knot selection mode didn't display the right selection intervals.
    
    - Replaced texture mode GL_MODULATE by GL_REPLACE in order for the curve selection areas to appear brighter and thus more visible.
