VisualBrush template in xaml

Question

hi
i'm creating a lib of hatch patterns as VisualBrush as a resource dictionary,
every things goes well so far, i have some questions ,
here is my code:

 <VisualBrush
         x:Key="VisualBrush.Hatch.Fill"
         TileMode="Tile"
         Viewbox="0,0,15,15"
         ViewboxUnits="Absolute"
         Viewport="0,0,15,15"
         ViewportUnits="Absolute">
            <VisualBrush.Visual>
                <Grid Background="Transparent">
                    <Path Data="M 0 15 L 15 0" Stroke="Gray" />
                    <Path Data="M 0 0 L 15 15" Stroke="Gray" />
                </Grid>
            </VisualBrush.Visual>
        </VisualBrush>

        <VisualBrush
         x:Key="VisualBrush.Hatch.Clay"
         TileMode="Tile"
         Viewbox="0,0,15,15"
         ViewboxUnits="Absolute"
         Viewport="0,0,15,15"
         ViewportUnits="Absolute">
            <VisualBrush.Visual>
                <Grid Background="Transparent">
                    <Path Data="M 0 15 L 15 0" Stroke="Gray" />
                </Grid>
            </VisualBrush.Visual>
        </VisualBrush>

        <VisualBrush
         x:Key="VisualBrush.Hatch.Silt"
         TileMode="Tile"
         Viewbox="0,0,10,10"
         ViewboxUnits="Absolute"
         Viewport="0,0,10,10"
         ViewportUnits="Absolute">
            <VisualBrush.Visual>
                <Grid Background="Transparent">
                    <Path
                     Data="M 5 0 L 0 5"
                     Stroke="Black"
                     StrokeThickness="0.5" />
                </Grid>
            </VisualBrush.Visual>
        </VisualBrush>

Q1: i want to do something similar to Style(or template) to extract the repeated (below) code out of each pattern.
// repeated code
TileMode="Tile"
Viewbox="0,0,15,15"
ViewboxUnits="Absolute"
Viewport="0,0,15,15"
ViewportUnits="Absolute"

Q2: i want to know what is the are the Viewport/ViewBox and what is the difference .
Q3: i want to know how to scale the pattern instead of define another one .

thanks in advance
