// This function was ripped off from win95

// WE ONLY SUPPORT DST_TEXT, and NO CALLBACKS!

//
//  DrawState()
//
//  Generic state drawing routine.  Does simple drawing into same DC if
//  normal state;  uses offscreen bitmap otherwise.
//
//  We do drawing for these simple types ourselves:
//      (1) Text
//          lData is string pointer.
//          wData is string length
//      (2) Icon
//          LOWORD(lData) is hIcon
//      (3) Bitmap
//          LOWORD(lData) is hBitmap
//      (4) Glyph (internal)
//          LOWORD(lData) is OBI_ value, one of
//              OBI_MENUCHECK
//              OBI_MENUBULLET
//              OBI_MENUARROW
//          right now
//
//  Other types are required to draw via the callback function, and are
//  allowed to stick whatever they want in lData and wData.
//
//  We apply the following effects onto the image:
//      (1) Normal      (nothing)
//      (2) Union       (gray string dither)
//      (3) Disabled    (embossed) 
//
//  Note that we do NOT stretch anything.  We just clip.
