[Bug] AvatarView using `StrokeShape` and `ImageSource` image is incorectly clipped

[GeorgeLeithead]

Description

AvatarView has a parent of Border and supports the Stroke* properties, as well as the AvatarView specific CornerRadius. When using StrokeShape to implement 'exotic' shapes, paired with ImageSource, the image is clipped to the CornerRadius and not the StrokeShape.

Steps to Reproduce

            <mct:AvatarView
                Grid.Row="1"
                Grid.Column="0"
                HeightRequest="48"
                SemanticProperties.Description="Sample AvatarView idea using a polyline stroke shape to override the corder radius to draw a star."
                StrokeShape="PolyLine 70,16 76,32 94,32 80,44 84,60 70,50 55,60 60,42 46,32 64,32"
                Style="{StaticResource Rating}"
                Text="1"
                ImageSource="avatar_icon.png"
                WidthRequest="48" />

Expected Behavior

ImageSource should be clipped to both the StrokeShape and CornerRadius depending on which is used.

Actual Behavior

ImageSource is currently only clipped to the control CornerRadius.

Question: If both are set, should CornerRadius override StrokeShape, or the other way around? I personally think that CornerRadius is the main property and should override. Opinions?

[GeorgeLeithead]

I have a partial working fork and branch, to where I can get the image clip to work correctly for Ployline, Ellipse, Path, Polygon and rectangle (default is RoundRectangle implemented by the CornerRadius).

Works for Android:

However, it does not work well for Windows:

It works for embedded images (row 2, control 1 and 3), but URL images (row 2, column 2) are a problem. I THINK the problem is that the clip is applied before the image completes download/stream, and then overrides the clip.

Thanks George! Could you open a draft PR for the bug fix?

I'll take a look at the code and see how I can help!

@GeorgeLeithead I see it is fixed for all platforms except windows. Does this issue describe the leftover for this bug? https://github.com/CommunityToolkit/Maui/issues/632
