The SetWidgetAlpha function sets the alpha channel of the widget color corresponding to the type specified by the type parameter. The type can be one of the following constants.

`kWidgetColorDefault`	The default color for the widget. This is usually equivalent to one of the other types of colors, but which one varies with the type of the widget. See the documentation for the individual `Widget` subclasses for information about the default color.
`kWidgetColorText`	The color of any text shown by the widget.
`kWidgetColorLine`	The color of any lines or strokes shown by the widget.
`kWidgetColorFill`	The color of any solid fills shown by the widget.
`kWidgetColorBorder`	The color of the widget's border.
`kWidgetColorBackground`	The color of the widget's background.
`kWidgetColorButton`	The color of any buttons belonging to the widget.
`kWidgetColorHilite`	The color used to highlight parts of the widget.
`kWidgetColorCaret`	The color of the insertion caret.
`kWidgetColorClear`	The clear color for viewport widgets.
`kWidgetColorGlyphEffect`	The color of glyph effects applied to text.

The red, green, and blue channels of the target color are not affected. If the widget does not support the color specified by the type parameter, then no change is made to any of the widget's colors.
