<!--- swatchview is a simple view that is filled with a single color.
    Either 'fgcolor' and 'bgcolor' may be used to set the color of the view.
    By default it fills the space of the parent with white -->

    <attribute name="ctransform" value="null"/>

    <!--- this is the color that was set (by setting 'bgcolor' or 'fgcolor' ),
        bgcolor may be different if setColorTransform has been called
        @keywords readonly -->
    <attribute name="color" value="0xffffff"/>

    <method name="construct" args="parent, args">

    <!--- setting the fgcolor attribute is equivalent to setting bgcolor

    <setter name="fgcolor" args="c">
        this.setAttribute('bgcolor', c);

    <!--- sets the bgcolor with the color transform applied

    <!--- affects the bgcolor, unlike in regular views where only the
        resource and subviews are affected by the color transform
