[Laszlo-dev] ColorTransform and LPP-7481

[Henry Minsky]

Maybe Max can help out here, I guess I don't really understand what
the fgcolor of a sprite is supposed
to be doing. The documentation in LzView says

/** A color to use to render object that appears inside this view,
  * which includes any vector or bitmap art in the view's resource
  * and any contained views.
  * @lzxtype color
  */
var fgcolor;

But the swf8 sprite implementation has this comment on setColor

/**
  * Sets the color of the view (the view's resource and any subviews) to the
  * the color given. This will completely override any color information in the
  * view or subview resources. Use the view method
  * <method>setColorTransform</method> to tint a view.
  * @param Integer c: A color in rgb format; for example, 0xff0000 is red.
  */


So is fgcolor  supposed to override any existing color, including the bgcolor?
