  gdi32/tests: Add tests for GdiTransparentBlt() with 32-bit DIB bitmaps.
  
  Test that the alpha channels in 32-bit DIB bitmaps are ignored in GdiTransparentBlt(). Also add
  tests to show that the alpha channels are not ignored when converting 32-bit DIB bitmaps to mono
  bitmaps. This suggests that the alpha channels are ignored in GdiTransparentBlt(), not when
  generating the mono mask bitmap.
