  * contrib/gtwvg/wvgparts.ch
    + Added: constants - WVG_IMAGE_ICONFILE
                         WVG_IMAGE_ICONRESOURCE
                         WVG_IMAGE_BITMAPFILE
                         WVG_IMAGE_BITMAPRESOURCE

  * contrib/gtwvg/pushbut.prg
    + Implemented: Display of Bitmaps or Icons on the pushbuttons
       from resources also. Before, it was available from disk files
       only. For this to happen a push button be created like this:

       WITH OBJECT oXbp := WvgPushButton():new()
          :pointerFocus := .F.
          :caption := { "Vouch", WVG_IMAGE_ICONFILE, IMAGE_VR }
          :border  := .F.
          :create( , , { {|| -( MaxRow() - 1 ) }, -31 }, { -2, -4 } )
          :activate := {|| hb_threadStart( {|| demoXbp() } ) }
          :toolTipText := "Flat Button . Lines: press ESC when finished."
       ENDWITH

       :caption := { [<cButtonText>], <nImageType>, <xImage> }
                =>
                   { "Vouch", WVG_IMAGE_ICONFILE, hb_dirBase() + "vr1.ico" }
                   { "Vouch", WVG_IMAGE_ICONRESOURCE, 212 /*Numeric ID in resource*/ }
                   { "Vouch", WVG_IMAGE_ICONRESOURCE, "VOUCHICO" /*Character ID in resource*/ }

       IMPORTANT - :caption has to be defined before :create() is called.

  * contrib/gtwvg/tests/demowvg.prg
    + Added: code to demonstrate above usage.
