[Feature Request] XAML Linear Gradient without Offset

[bbenetskyy]

We should provide support for XAML Linear Gradients without a defined Offset.

It should work the same as it is for CSS Linear Gradients - divide into equal parts between each color

Mean it should work the same as defined equal Offset between each color

Gradient of next code should have same result after implementation this feature:

<magicGradients:GradientView VerticalOptions="FillAndExpand">
    <magicGradients:GradientView.GradientSource>
        <magicGradients:LinearGradient Angle="352" IsRepeating="False">
            <magicGradients:GradientStop Color="#E91C83" Offset="0"/>
            <magicGradients:GradientStop Color="#E9631C" Offset="0.5"/>
            <magicGradients:GradientStop Color="#C0E91C" Offset="1"/>
        </magicGradients:LinearGradient>
    </magicGradients:GradientView.GradientSource>
</magicGradients:GradientView>

<magicGradients:GradientView VerticalOptions="FillAndExpand">
    <magicGradients:GradientView.GradientSource>
        <magicGradients:LinearGradient Angle="352" IsRepeating="False">
            <magicGradients:GradientStop Color="#E91C83" />
            <magicGradients:GradientStop Color="#E9631C" />
            <magicGradients:GradientStop Color="#C0E91C" />
        </magicGradients:LinearGradient>
    </magicGradients:GradientView.GradientSource>
</magicGradients:GradientView>

And looks like:

Now it looks like:
