    Makes a new Custom Dialog with the title 'My Custom Dialog' and a message 'This is a custom dialog with a message and an image above.', with dimensions of 300 by 200 pixels.
    Other styling options are grabbed from '$sync.Form.Resources' global variable.

    .EXAMPLE
    $foregroundColor = New-Object System.Windows.Media.SolidColorBrush("#0088e5")
    $backgroundColor = New-Object System.Windows.Media.SolidColorBrush("#1e1e1e")
    $linkForegroundColor = New-Object System.Windows.Media.SolidColorBrush("#0088e5")
    $linkHoverForegroundColor = New-Object System.Windows.Media.SolidColorBrush("#005289")
    Show-CustomDialog -Title "My Custom Dialog" -Message "This is a custom dialog with a message and an image above." -Width 300 -Height 200 -ForegroundColor $foregroundColor -BackgroundColor $backgroundColor -LinkForegroundColor $linkForegroundColor -LinkHoverForegroundColor $linkHoverForegroundColor

    Makes a new Custom Dialog with the title 'My Custom Dialog' and a message 'This is a custom dialog with a message and an image above.', with dimensions of 300 by 200 pixels, with a link foreground (and general foreground) colors of '#0088e5', background color of '#1e1e1e', and Link Color on Hover of '005289', all of which are in Hexadecimal (the '#' Symbol is required by SolidColorBrush Constructor).
    Other styling options are grabbed from '$sync.Form.Resources' global variable.
