How to change watermark foreground/opacity or override style ?

[punker76]

@kzanderoff The foreground can be changed with the MahApps.Brushes.TextBlock.FloatingMessage brush and the font size with the MahApps.Font.Size.FloatingWatermark resource key.

Example with the current develop resource keys:

<Application.Resources>
    <SolidColorBrush x:Key="MahApps.Brushes.TextBlock.FloatingMessage" Color="OrangeRed" />
    <x:Double x:Key="MahApps.Font.Size.FloatingWatermark">11</x:Double>
</Application.Resources>

<TextBox mah:TextBoxHelper.UseFloatingWatermark="True"
         mah:TextBoxHelper.Watermark="User name" />

If you also want to change opacity, override MahApps.Styles.TextBlock.Watermark and/or MahApps.Styles.TextBlock.AutoCollapsing, because both are defined with Opacity="0.6" on current develop.
