Silverlight 苹果风格按钮Mac OS Style 实现的更新版

在 Silverlight 2 beta 2 时，我曾经写了一篇帖子实现了苹果风格的按钮样式（ Silverlight 下苹果 (Mac OS)风格按钮的实现）。

而现在 Silverlight 2 终于发布了，也给之前的代码带来了很多问题，导致无法继续使用。

经过一阵探索，我终于成功修改了这个代码，现在在正式版下也能工作正常了。其关键点如下：
1. 在 beta 2 时，需要采用 <vsm:Setter> 和 <vsm:Style> 的语法编写样式。其中 vsm 是个名称空间引用：
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
而正式版下直接用 <Style> 和 <Setter> 表签即可。
这个问题如果不修改，程序可以编译通过，但是运行时会报一个莫名其妙的 “ AG_E_PARSER_PROPERTY_NOT_FOUND ”错误。

2. ContentPresenter 和 ContentControl 控件删除了如下属性：
Textdecorations,
textwrapping,
TextAlignment.
因此，现在必须在 template 中将 ContentPresenter 的定位改用容器 Button 的 HorizontalContentAlignment 和 VerticalContentAlignment 属性来控制。代码如下：

< ContentPresenter Margin= "4,5,4,4" Content= "{TemplateBinding Content}" ContentTemplate= "{TemplateBinding ContentTemplate}" HorizontalAlignment= "{TemplateBinding HorizontalContentAlignment}" VerticalAlignment= "{TemplateBinding VerticalContentAlignment}" />

修改成功后的 Style 全部代码如下：
