[vtkusers] Remove white outline on slider text

[Frederic Perez]

Hello David,

probably the key is to retrieve the properties of the text associated with
the slider and modify it (with ShadowOff).

I found this code of mine---perhaps it might help, I'm not sure:

    void
    SetSomeTextProperties(
        vtkTextProperty* a_pTextProperty,
        size_t a_nTextSize,
        double a_d3TextColor[3])
    {
        if (!a_pTextProperty)
            return;
        a_pTextProperty->SetFontFamilyToArial();
        a_pTextProperty->BoldOff();
        a_pTextProperty->ItalicOff();
        *a_pTextProperty->ShadowOff();*
        a_pTextProperty->SetFontSize(a_nTextSize);
        // '- Fails to work (?).
        //    See http://markmail.org/message/xyx2y7cdwuj3aw55
        a_pTextProperty->SetColor(a_d3TextColor);
        a_pTextProperty->SetJustificationToCentered();
        //a_pTextProperty->SetVerticalJustificationToCentered();
    }

Regards,

Frederic Perez
