    BUG #14828: Keep surface color from interacting with scalar color. · daf8c6e7
    Utkarsh Ayachit authored
    When using scalar coloring, if vtkScalarsToColorsPainter decided to use
    a texture for mapping the scalars to colors, we ended up with the
    surface color bleeding through the texture. This commit ensures that
    such bleeding is avoided.
    We don't simply use glTexEnvf (GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE,
    GL_REPLACE), since that results in the diffuse highlights being lost.
    By enabling GL_COLOR_MATERIAL and calling glColor3f(1,1,1), we follow
    the same lighting/coloring path as we would when not using the texture
    for scalar coloring.
