DC here's the Constants

  RASTERCAPS = 38,
  RC_BANDING = 2,
  RC_BITBLT = 1,
  RC_BITMAP64 = 8,
  RC_DI_BITMAP = 128,
  RC_DIBTODEV = 512,
  RC_FLOODFILL = 4096,
  RC_GDI20_OUTPUT = 16,
  RC_PALETTE = 256,
  RC_SCALING = 4,
  RC_STRETCHBLT = 2048,
  RC_STRETCHDIB = 8192,
  RC_DEVBITS =  #8000,
  RC_OP_DX_OUTPUT =  #4000,
